Description
There is a cricket that lives by our timeshare in Myrtle Beach, South Carolina. Most every night I hear it patiently chirping away. Some nights it chirps faster than others, and it seems like the warmer it is, the faster it chirps. There are many crickets, and each of them seems to behave the same. On several different nights, armed with a stopwatch and a thermometer, I recorded the frequency of the chirps and compared it to that night's air temperature.
Experimental Results
The chirping follows a simple linear formula: take the number of chirps, add 40 and divide that sum by four to get the temperature in degrees Fahrenheit.
Assignment
Create a simulation to model the crickets chirping at various randomly generated frequencies, create an Environmentclass that knows and can return the current temperature. Create a Cricket class that chirps, or for simplicity, returns how many chirps per minute the cricket would make at that temperature. Repeat the simulation for at least three trials.
Extension: There is a cricket variety in some parts of South Carolina that is a little slower than most normal Carolina crickets. Add a ClemsonCricket class that extends Cricket but chirps slower by 20%.
Bonus: Implement polymorphism in the driver class.
Rubrics
Cricket class should include the following items:
A variable that stores the frequency of chirps.
A default constructor that initializes the frequency to a random value
An overloaded constructor that initializes the frequency to a value of your choice that gets passed on as a parameter.
A method for changing the frequency to a random value.
A getter method that returns the frequency.
clemsonCricket class should include the following items:
A default constructor that initializes the frequency to a random value that is 20% lower than what the parent class constructor would initialize it to.
A overloaded constructor that calls to the parent constructor.
A polymorphic method that changes the frequency value to a value that is 20% lower than what the parent method would change it to.
Environment class should include the following items:
A variable that stores the temperature.
A default constructor that initializes the temperature to a value of your choosing.
An overloaded constructor that initializes the temperature based on the formula in the assignment.
A method that takes in a frequency as a parameter and calculates the temperature based on the formula in the assignment.
testCrickets program should do the following items:
Creates an Environment object in the test program or in the Cricket or clemsonCricket classes and displays temperature Creates a cricket object and displays temperature before and after changing frequency
Creates a Clemson cricket object and displays temperature before and after changing frequency
Creates a polymorphic Clemson cricket object and displays temperature before and after changing frequency.

This was a quiz that I submitted earlier in the semester but I had not received full points due to a coding mistake. Below, I will provide the instructions and the code that needs to be changed in order for the program to work. Any place that has a "// Student Code Here" or "// Test Your Methods Here" must be changed accordingly.------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------INSTRUCTIONS:Step 1Fill in the doubleOrNothing method, which takes an int as a parameter. If the number is less than 100, return that number doubled. Otherwise, return zero.For example, passing 4 to this method would return 8, but passing 104 to this method would return 0.Step 2Fill in the formatPercentmethod, which takes a double as a parameter that represents a percent value between 0 and 1. This method returns a String that is the percentage between 0 and 100 percent, with one place following the decimal before a '%'.For example, passing the double '.85' would return the string "85.0%".Step 3Fill in the everyOtherChar method, which takes a String parameter called word*. This method returns an int which computes the sum of the ASCII values of *every other* character in the parameter word, starting with the first character.For example, passing the word "yam" into the method would tally the ASCII value of the characters 'y' and 'm', which have ASCII values of 121 and 109 respectively, so the method would return 230.Test Your MethodsTest your methods by calling them within main. You may run your program in Develop mode as many times as you would like, but you may only submit your program once.------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------CODE:public class quiz1 { // Step 1 public static int doubleOrNothing(int num) {e // student code here } // Step 2 public static String formatPercent(double percent) { // student code here } // Step 3 public static int everyOtherChar(String word) { // student code here } public static void main(String [] args) { // test your methods here! }}

a one-two paragraph summary on the Running Queries and Reports tutorials. Apply critical thinking and an academic writing style that demonstrates your understanding of the difference between a Microsoft Access database and an Excel spreadsheet by comparing the features of each and when they would be used as personal computer applications if applicable.
Answers
Explanation:
Both perform almost the same function of storing data, performing numerical calculations, formating cells, and to generate reports.
However, when dealing with data that is short term (requiring less updating) Microsoft Excel is recommended as it provides easy spreadsheet functions. Access on the other hand is a more complex application for data analysis involving constantly changing data values that are long term based. Access allows for efficient data analysis using complex tools such as import module, automated queries etc.

This acquisition happens very quickly and on day one the business needs people at Uni-Tech to connect to hosts at Acme using hosts names that can be resolved by Active Directory. Describe a method for integrating the two environments that does not require too many individual tasks that will take many hours
Answers
Answer: provided in the explanation section
Explanation:
Network Merging and Acquisitions
Environment:
· 400 Windows Servers
· 8000 Windows client devices (laptops running Windows os)
· 40 Linux servers Active Directory Domain Services to provide DNS services to all the hosts, both Windows and Linux.
· Unix servers(Other environment to be merged)
· host resolution they use is BIND
A great challenge of managing a network at a growing company is that of acquisitions. That is, one of the ways a developing company grows is by acquiring other companies. When that acquisition happens, there is usually the require to connect the two networks together.
Connecting two networks environments together is one of those tasks that makes network engineers groan. As networks are not built to any type of agreed-upon norm, what the opposite network will hold is always unpredictable, most probably in a difficult-to-integrate way.
Quick & Dirty IPSEC Tunnel
When an acquisition deal happen, management needs the IT infrastructures connected. The proper way of bringing networks together involves a full audit of the remote network to insure compliance with regulatory obligations, inventorying IP address blocks both public and private and BGP ASNs in use, understanding IGP routing schemes, reviewing WAN provider contracts, itemizing hardware and software in use, purchasing needed equipment, staging infrastructure changes, scheduling maintenance windows, and so on.
Main problems with quick and dirty IPSEC tunnels are
Maintaining network lists manually.
manual maintenance of route injection into the IGP.
Probable single points of failure.
Using SD-WAN As Acquisition Network Glue:
Thinking through SD-WAN technology, quick connectivity option that’s better than a quick and dirty IPSEC tunnel. SD-WAN offers
1. Easily managed redundant plumbing :
SD-WAN forms a mesh of tunnels on top of all available paths. That means that a local circuit outage neither takes down the ability to forward nor needs a network engineer to re-configure IP tunnel endpoints.
2. IGP integration:
When route injection is often available with IPSEC tunnels, it is found that route injection is not terribly reliable, depending on vendor, software version, and a host of other factors. I have not been keen to rely on routes being injected or withdrawn by an IPSEC VPN endpoint.
3. Segment isolation:
An SD-WAN function available from many of SD-WAN vendors is that of segment isolation. You can create virtual network segments that permit intra-segment communication while preventing inter-segment communication. In the case of an acquisition, that functionality seems really helpful.
Segment isolation can also help simplify routing. If you’re facing overlapping, this might help avoid a complex NAT scheme.
4. Service chaining:
Many SD-WAN products shows service chaining. That is, SD-WAN devices tunnel between each other. By seeing the tunnelling ability, it’s possible to drop traffic off when we need.
Drawbacks Of The SD-WAN Approach
A few drawbacks in using SD-WAN as a network merger tool come to mind.
Cost:
The cost of adding a new network segment to an SD-WAN deployment varies by licensing scheme, but is not at all free. Quick and dirty IPSEC tunnels often are free which requires no capital expense to stand up.
Remote hands:
In order to leverage SD-WAN at remote sites, there is a great chance you’ll need remote hands to pull off the device installation. That’s not anything else than deploying SD-WAN in your own network
Perhaps not quick and dirty enough:
The great problem facing around is the long time it takes to stand up dedicated WAN circuits. IPSEC tunnels are often the path of very less resistance to bringing up a private connection between two newly acquainted organizations.
To Conclude:
Using IPSEC tunnels to join networks together what will eventually be part of a unified IT whole isn’t a mature solution in the modern era. SD-WAN looks like a mature solution that do not need require private MPLS circuits to function.
If private MPLS circuits are eventually added to the SD-WAN mix, technology transition is not required. The SD-WAN option can stay in place as-is, using the MPLS circuit being added to the SD-WAN forwarding device as a newly available path. That means the temporary solution can transition into the permanent solution by grace.
SD-WAN can be opted as a way to onboard an acquired network permanently, at the same time retaining the fast time to connect that an IPSEC tunnel offers. For organizations who already have an SD-WAN solution in place, there is nothing to think about. Considering organizations who haven’t invested in SD-WAN so far, this might be an additional driver to do so.
Write a program that first calls a function to calculate the square roots of all numbers from 1 to 1,000,000 and write them to a file named: roots.txt (See output on page 3) 2.) Write a program then calls a function to calculate the squares of all numbers from 1 to 1,000,000 and write them to a file named: squares.txt 3.) Here are the function prototypes: void writeRoots(); void writeSquares();
Answers
Answer:
The csharp program to compute square roots of numbers and write to a file is as follows.
class Program
{
static long max = 1000000;
static void writeRoots()
{
StreamWriter writer1 = new StreamWriter("roots.txt");
double root;
for (int n=1; n<=max; n++)
{
root = Math.Sqrt(n);
writer1.WriteLine(root);
}
}
static void Main(string[] args)
{
writeRoots();
}
}
The program to compute squares of numbers and write to a file is as follows.
class Program
{
static long max = 1000000;
static void writeSquares()
{
StreamWriter writer2 = new StreamWriter("squares.txt");
long root;
for (int n = 1; n <= max; n++)
{
root = n*n;
writer2.WriteLine(root);
}
}
static void Main(string[] args)
{
writeSquares();
}
}
Explanation:
1. An integer variable, max, is declared to hold the maximum value to compute square root and square.
2. Inside writeRoots() method, an object of StreamWriter() class is created which takes the name of the file as parameter.
StreamWriter writer1 = new StreamWriter("roots.txt");
3. Inside a for loop, the square roots of numbers from 1 to the value of variable, max, is computed and written to the file, roots.txt.
4. Similarly, inside the method, writeSquares(), an object of StreamWriter() class is created which takes the name of the file as parameter.
StreamWriter writer2 = new StreamWriter("squares.txt");
5. Inside a for loop, the square of numbers from 1 to the value of the variables, max, is computed and written to the file, squares.txt.
6. Both the methods are declared static.
7. Inside main(), the method writeRoots() and writeSquares() are called in their respective programs.
8. Both the programs are written using csharp in visual studio. The program can be tested for any operation on the numbers.
9. If the file by the given name does not exists, StreamWriter creates a new file having the given name and then writes to the file using WriteLine() method.
10. The csharp language is purely object-oriented language and hence all the code is written inside a class.
The first programming project involves writing a program that computes the minimum, the maximum and the average weight of a collection of weights represented in pounds and ounces that are read from an input file. This program consists of two classes. The first class is the Weight class, which is specified in integer pounds and ounces stored as a double precision floating point number. It should have five public methods and two private methods:
A public constructor that allows the pounds and ounces to be initialized to the values supplied as parameters.
A public instance method named lessThan that accepts one weight as a parameter and returns whether the weight object on which it is invoked is less than the weight supplied as a parameter.
A public instance method named addTo that accepts one weight as a parameter and adds the weight supplied as a parameter to the weight object on which it is invoked. It should normalize the result.
A public instance method named divide that accepts an integer divisor as a parameter. It should divide the weight object on which the method is invoked by the supplied divisor and normalize the result.
A public instance toString method that returns a string that looks as follows: x lbs y oz, where x is the number of pounds and y the number of ounces. The number of ounces should be displayed with three places to the right of the decimal.
A private instance method toOunces that returns the total number of ounces in the weight object on which is was invoked.
A private instance method normalize that normalizes the weight on which it was invoked by ensuring that the number of ounces is less than the number of ounces in a pound.
Both instance variable must be private. In addition the class should contain a private named constant that defines the number of ounces in a pound, which is 16. The must not contain any other public methods.
The second class should be named Project1. It should consist of the following four class (static) methods.
The main method that reads in the file of weights and stores them in an array of type Weight. It should then display the smallest, largest and average weight by calling the remaining three methods. The user should be able to select the input file from the default directory by using the JFileChooser class. The input file should contain one weight per line. If the number of weights in the file exceeds 25, an error message should be displayed and the program should terminate.
A private class method named findMinimum that accepts the array of weights as a parameter together with the number of valid weights it contains. It should return the smallest weight in that array.
A private class method named findMaximum that accepts the array of weights as a parameter together with the number of valid weights it contains. It should return the largest weight in that array.
A private class method named findAverage that accepts the array of weights as a parameter together with the number of valid weights it contains. It should return the average of all the weights in that array.
Be sure to follow good programming style, which means making all instance variables private, naming all constants and avoiding the duplication of code. Furthermore you must select enough different input files to completely test the program.

Write a program that calculates and displays a person’s body mass index (BMI). The BMI is often used to determine whether a person with a sedentary lifestyle is overweight or underweight for his or her height. A person’s BMI is calculated with the following formula:
BMI = weight x 703 / height2
where weight is measured in pounds and heightis measured in inches. The program should ask the user to enterhis/her weight and height. The program should display a message indicating whether the person has optimal weight, is underweight, or is overweight. A sedentary person’s weight is considered optimal if his or her BMI is between18.5 and 25. If the BMI is less than 18.5, the person is considered underweight.

It could be an inbuilt feature like "Snipping Tool" which is seen in the Windows operating system by default (from Windows 7 and upward); this feature is however not restricted to only Windows operating systems. It could also be a third party app to capture onscreen processes.
Smart Art is a visual representation of data and information which is made by choosing a layout that best suits the information you are projecting.

All these options (A - D) are good ways of enhancing a presentation. However, to get a snapshot of an onscreen process from the desktop, Option D (Screen Clipping) is the correct answer
a. Create a console-based application named Desks that computes the price of a desk and whose Main() method calls the following methods:
• A method to accept the number of drawers in the desk as input from the keyboard. This method returns the number of drawers to the Main() method.
• A method to accept as input and return the type of wood—‘m’ for mahogany, ‘o’ for oak, or ‘p’ for pine.
• A method that accepts the number of drawers and wood type, and calculates the cost of the desk based on the following:
• Pine desks are $100.
• Oak desks are $140.
• All other woods are $180.
• A $30 surcharge is added for each drawer.
• This method returns the cost to the Main() method.
• A method to display all the details and the final price.

Write a cout statement that uses the setw manipulator to display the number variable with a field width of 4. Do not use an endl manipulator in your statement. (Assume the program includes the necessary header file for the setw manipulator.)
Answers
Answer:
Following are the statement in C++ Programming language
cout<<setw(4);// set the width
cout<<number; // print the number with the width of 4
Explanation:
The setw() is setting according to the width defined as the argument to the function .The setw() is under the ios header library .It means its definition is under the ios header file .
Following are the syntax to defined the setw() function that are given below
setw(int k)
For example
include <iomanip> // header file
#include <ios> // header file
#include <iostream> // header file
using namespace std; // namespace
int main() // main function
{
int number = 60;// variable declaration
cout << "previous width:" << number; // print
cout << " After setting the width"<< setw(4);
cout << number; // display number
return 0;
}

Solution:
Here, our fundamental aim is to look for the content which is having single space between different sentences. As it sentences finishing with . Going before with single and various spaces we have to channel and match just e the sentences which are finishing with ". "
For this we use order called "GREP" in Unix. "GREP " represents worldwide quest for standard articulation. This order is utilized inquiry and print the lines that are coordinating with determined string or an example. The example or indicated string that we have to look through we call it as customary articulation.
Syntax of GREP:
GREP [OPTIONS] PATTERN [FILE_NAME]
For our solution please follow the command
GREP "*\•\s$" userNotes.txt
Now it will display a all the lines having . Followed by single space.

You are given a string of n characters s[1 : : : n], which you believe to be a corrupted text document in which all punctuation has vanished (so that it looks something like itwasthebestoftimes...). You wish to reconstruct the document using a dictionary, which is available in the form of a Boolean function dict(): for any string w, dict(w) = true if w is a valid word false otherwise . (a) Give a dynamic programming algorithm that determines whether the string s[] can be reconstituted as a sequence of valid words. The running time should be at most O(n2), assuming calls to dict take unit time. (b) In the event that the string is valid, make your algorithm output the corresponding sequence of words.

Explanation:
Given that:
Assume D(k) =║ true it is [1 : : : k] is valid sequence words or false otherwise
To determine D(n)now the sub problem s[1 : : : k] is a valid sequence of words IFF s[1 : : : 1] is a valid sequence of words and s[ 1 + 1 : : : k] is valid word.
So, from here we have that D(k) is given by the following recorance relation:

3. In a 32-bit CPU, the largest integer that we can store is 2147483647. Verify this with a
pseudocode and explain your logic.
Answers
Answer:
No, it can't be verified with a pseudocode.
Explanation:
We can not verify this with a pseudocode because the largest integer that we can store in 32-bit integer goes by the formula 2^32 - 1 = 4, 294, 967,295 and this means that it has 32 ones. Or it may be 2^31 - 1 = 2, 147, 483,647 which is a two complement signed integer.
Despite the fact that it can not be verified by using pseudocode, we can do the Verification by writting programs Through some programming language or in plain English code.
In a 32-bit CPU, the largest integer that we can store is 2147483647 because we can store integer as 2^31 and - (2^31 + 1).
The Sleeping-Barber Problem:
A barbershop consists of a waiting room with n > 0 chairs and the barber room containing the barber chair.
If there are no customers to be served, then the barber sleeps.
If a customer enters the barbershop and all chairs are occupied, then the customer leaves the shop.
If the barber is busy but chairs are available, then the customer sits in one of the free chairs.
If the barber is asleep, then the customer wakes up the barber and the shaving process begins.
After they finish, the customer leaves and the barber start shaving another customer, if there are any in the waiting room. Otherwise he goes to sleep.

Assume a user datagram connection sending 500 bytes to a client. the first byte is numbered 501. what is the sequence number of the segment if all data is sent in only one segment?
Answers
Answer:
501.
Explanation:
In Transmission Control Protocol (TCP), sending and receiving of data is done as byte. These bytes are eventually grouped into packets referred to as segment.
The sequence number of the segment if all data is sent in only one segment is the same as the first byte of that segment.
In this scenario, a user datagram connection is sending 500 bytes to a client and the first byte is numbered 501. Thus, if all data is sent in only one segment, the sequence number of the segment is 501. The 501 represents the initial segment number (ISN).
However, assuming the same data was sent in five (5) segments. The sequence number would be;
First segment (1st) = 501.
Second segment (2nd) = 1501.
Third segment (3rd) = 2501.
Fourth segment (4th) = 3501.
Fifth segment (5th) = 4501.
A retail company assigns a $5000 store bonus if monthly sales are $100,000 or more. Additionally, if their sales exceed 125% or more of their monthly goal of $90,000, then all employees will receive a message stating that they will get a day off. When your pseudocode is complete, test the following monthly sales and ensure that the output matches the following. If your output is different, then review your decision statements.
Monthly Sales Expected Output
monthlySales 102500 You earneda $5000 bonus!
monthlySales = 90000
monthlySales 112500 You earned a $5000 bonus!
All employees get one day off!
Answers
Answer:
To answer this question, i prepared a pseudocode and a program written in python;
Pseudocode begins here:
1. Start
2. Input montlySales
3. If monthlySales < 100000
3.1. Display Nothing
4. Else
4.1 Display “You earned a $5000 bonus!”
4.2 If monthlySales > 1.25 * 90000
4.2.1 Display “All employees get one day off!”
5. Stop
Python Program starts here (See attachment for proper view of the program):
#Prompt user for input
monthlySales = float(input("Monthly Sales: "))
#Check monthlySales
if monthlySales < 100000:
print("")
else:
print("You earned a $5,000 bonus")
if monthlySales > 1.25 * 90000:
print("All Employees get the day off")
Explanation:
To answer this question, a conditional if statement is needed.
The pseudocode (and the program) starts by prompting user for input;
Then, the user input is first compared with 100,000
If it's less than 100,000; then nothing is displayes
However, if it is at least 100,000
"You earned a $5,000 bonus" is displayed
It further checks if the user input is greater than 125% of 90,000
If yes, "All Employees get the day off" is displayed else, nothing is displayed.
The pseudocode (and the program) stops execution, afterwards

A Food organization's payroll system is in such a way that it pays its employees as shift managers fixed weekly salary and hourly workers fixed hourly wage for up to the first 60 hours they
work and if they work more than 60 hrs , it is considered as overtime and paid 2.5 times their hourly wages. Commission workers get $400 plus 2.8% of their gross weekly sales. Write a program to compute the weekly pay for each employee. Each type of employee has its own pay code: Shift Managers have paycode 1, hourly workers have code 2, and commission workers have code 3 .Use a switch to compute each employee’s pay based on that employee’s paycode. Within the switch, prompt the user (i.e., the payroll clerk) to enter the appropriate facts your program needs to calculate each employee’s pay based on that employee’s pay code.
Sample Output
Enter employee's number code: 2
Enter hourly worker's pay rate: 12.25
Enter the number of hours worked: 100
Weekly pay is: 1592.50

Implement a Java program using simple console input & output and logical control structures such that the program prompts the user to enter a 5 digit integer as input and does the following tasksThe program checks whether the input number is a palindrome or not and prints the result of this palindrome check. A number is a palindrome if it reads the same backward as forward. For example, each of the following five-digit integers is a palindrome: 12321, 55555, 45554 and 11611; whereas 12312, 55565, 45545 and 11621 are not a palindrome. Your program should print "The number is palindrome" or "The number is not palindrome" after checking the input number.The program checks whether the input number has 5 digits or not and prints the error message "Invalid number" if the input number is not a 5 digit one.I posted my code below, I think I have a good start with reversing the number but I'm not sure how to implement the portion of how to actually check if it is a palindrome.import java.util.Scanner;public class Problem2 {public static void main(String[] args){int number;
Scanner scanner = new Scanner(System.in);System.out.println("Enter a positive integer between 1 and 5 digits long that you would like to test for a palindrome: ");num = in.nextInt();for( ;num != 0; ){reversenum = reversenum * 10;reversenum = reversenum + num%10;num = num/10;
Answers
Answer:
import java.util.Scanner;
import java.util.regex.*;
public class Problem2 {
public static void main(String[] args)
{
int number;
Scanner scanner = new Scanner(System.in);
System.out.println("Enter a positive integer with exactly 5 digits long that you would like to test for a palindrome: ");
String str = scanner.nextLine();
int len = str.length();
if (!Pattern.matches("^[1-9]\\d{4}$", str)) {
System.out.println("Invalid number");
} else {
boolean isPalindrome = true;
for(int i=0; i<len/2; i++) {
if (str.charAt(i) != str.charAt(len-i-1)) {
isPalindrome = false;
break;
}
}
if (isPalindrome) {
System.out.println("The number is palindrome");
} else {
System.out.println("The number is not palindrome");
}
}
}
}
Explanation:
Even though the problem talks about numbers, a palindrome check is more about strings, so that's how I'd handle it. I check the validity of the input using a regular expression (note how I don't allow the number to start with a zero, you can change that if you want), and then I check for palindrome to iterating to only halfway the string, and checking the i-th position ffrom the start against the i-th position from the end. If there is no match, the loop is aborted.
See that also for even-length palindromes this will work.
The ability to write functions is one of the more powerful capabilities in C++. Functions allow code to be reused, and provides a mechanism for introducing the concept of modularity to the programming process. In addition to the concept of functions, C++ allows complex programs to be organized using header files (.h files) that contain the prototypes of functions and implementation files that (.cpp files) that contain the implementation (definition) of the functions.
In this programming assignment you will be asked to implement a number of useful functions using a header file and an implementation file. You will place the prototypes for your function in a .h file, and implement these functions in a .cpp file. You will need to write a driver (a program designed to test programs) to test your functions before you upload them.

The header file in C++ is as follows
myFunction.h
void max(int a, int b)
{
if(a>b)
{
std::cout<<a;
}
else
{
std::cout<<b;

}
The Driver Program is as follows:
#include<iostream>
#include<myFunction.h>
using namespace std;
int main()
{
int m,n;
cin>>m;
cin>>n;
max(m,n);
}
Explanation:
It should be noted that, for this program to work without errors, the header file (myFunction.h) has to be saved in the include directory of the C++ IDE software you are using.
For instance; To answer this question I used DevC++
So, the first thing I did after coding myFunction.h is to save this file in the following directory ..\Dev-Cpp\MinGW64\x86_64-w64-mingw32\include\
Back to the code
myFunction.h
void max(int a, int b) {
-> This prototype is intialized with integer variables a and b
if(a>b) -> If the value of a is greater than b;
{
std::cout<<a; -> then the value of variable a will be printed
}
else
-> if otherwise,
{
std::cout<<b;
-> The value of b will be printed
}
}
Driver File (The .cpp file)
#include<iostream>
#include<myFunction.h> -> This line includes the uesr defined header
using namespace std;
int main()
{
int m,n; -> Two integer variables are declared
cin>>m; -> This line accepts first integer input
cin>>n; -> This line accepts second integer input
max(m,n);
-> This line calls user defined function to return the largest of the two integer variables
