Write a program to simulate a simple calculator. In your program ask the user to enter an operation selected from the menu, ask for two operands. Calculate the result and display it on the screen. Here is a sample run
Answer:
Written in Python:
opcode = input("Enter operator: +,-,*,/")
operand1 = float(input("Operand 1: "))
operand2 = float(input("Operand 2: "))
if opcode == "+":
print(operand1 + operand2)
elif opcode == "-":
print(operand1 - operand2)
elif opcode == "*":
print(operand1 * operand2)
elif opcode == "/":
print(operand1 / operand2)
else:
print("Invalid Operator")
Explanation:
This prompts user for operator
opcode = input("Enter operator: +,-,*,/")
The next two lines prompt user for two operands
operand1 = float(input("Operand 1: "))
operand2 = float(input("Operand 2: "))
This performs + operation if operator is +
if opcode == "+":
print(operand1 + operand2)
This performs - operation if operator is -
elif opcode == "-":
print(operand1 - operand2)
This performs * operation if operator is *
elif opcode == "*":
print(operand1 * operand2)
This performs / operation if operator is /
elif opcode == "/":
print(operand1 / operand2)
This displays invailid operator if input operator is not +,-,* or /
else:
print("Invalid Operator")

Write a class named TestScores. The class constructor should accept an array of test scores as its argument. The class should have a method that returns the average of the test scores. If any test score in the array is negative or greater than 100, the class should throw an IllegalArgumentException. Demonstrate the class in a program.
import java.util.Arrays;
public class TestScores {
public static float getAverage(float arr[]){
float total = 0;
for (float x : arr){
if (x < 0 || x > 100){
throw new IllegalArgumentException();
}
else{
total += x;
}
}
return (total / arr.length);
}
public static void main(String [] args){
float arr[] = {1,100,0,43,-1};
System.out.println(getAverage(arr));
}
}
In the main method we test our getAverage method with the arr array. You can replace the values in the arr array and test your own values. I hope this helps!
The code example of the implementation of the TestScores class in Java is shown below:
What is the class?java

Answer:
D. digital logic level through machine levels
Explanation:
In Computer science, the modern computer systems are basically organized in levels and this is known as computer hierarchy. The three levels in a chronological order are operating system level, machine language level and digital (hardware) logic level.
A digital logic level is the most fundamental level of a computer and can be defined as a level of the computer hierarchy which typically comprises of wires and gates. In digital circuits, the two (2) main logic level of the binary logic state are logical low and logical high which is typically denoted by the number 0 and 1 respectively.

Write a method getIntVal that will get the correct value input as integer numbers from the user. The input will be validated based on the first two numbers received as parameters.
Complete Question:
Write a method getIntVal that will get the correct value input as integer numbers from the user. The input will be validated based on the first two numbers received as parameters.
In other words, your program will keep asking for a new number until the number that the user inputs is within the range of the <firstParameter> and <secondParameter>.
The method should present a message asking for the value within the range as:
Please enter a number within the range of (<firstParameter> and <secondParameter>):
Note that <firstParameter> should be changed by the value received as that parameter and <secondParameter> as well.
If the user inputs a value that it is lower than the first value, the program will show the message:
The input number is lower than <firstParameter>
Note that <firstParameter> should be changed by the value received as that parameter
If the user inputs a value that it is greater than the first value, the program will show the message:
The input number is greater than <secondParameter>
Note that <secondParameter> should be changed by the value received as that parameter.
You do not need to modify anything in the main method, you just need to write the missing parts of your new getIntVal method.
Answer:
#include<iostream>
using namespace std;
void getIntVal(int num1, int num2) {
int num;
cout<<"Please enter a number within the range of "<<num1<<" and "<<num2<<": ";

How long will it take to send 1.1 million bits using the Stop and Wait ARQ protocol if each packet contains 1000 bits and the only delay is propagation delay
Answer:
1.111 second
Explanation:
We know propagation speed = [tex]$2 \times 10^8$[/tex] m/s
= [tex]$2 \times 10^5$[/tex] km/s
One packet size = 1000 bit
Distance between sender and the receiver = 1000 m = 1 km
The channel data rate = 1 Mbps = [tex]$1 \times 10^6$[/tex] bits per sec
There is no transmission delays of ACKs,
The time to transmit one data packet = [tex]$T_{trans}+2T_{prop}$[/tex]
Here, time to transmit frame = [tex]$T_{trans}$[/tex]
propagation time = [tex]$T_{prop}$[/tex]
Therefore, [tex]$T_{trans}$[/tex] = [tex]$\frac{bits\ per\ frame}{transmission \ speed}$[/tex]
= [tex]$\frac{1000}{1 \times 10^6}$[/tex] = 0.001 seconds
[tex]$T_{prop}=\frac{distance\ between\ sender\ and\ receiver}{propagation \ speed}$[/tex]
= [tex]$\frac{1}{2 \times 10^5}$[/tex]
= 0.000005 seconds
Therefore, T = 0.001 +2(0.000005)
= 0.00101 seconds
We known, 1.1 million bits= 1100 packets
Therefore to transmit 1 million bits = 1100 x 0.00101
= 1.111 second
