Answer:

When you try to print values from the array before setting free the memory previously allocated, it will return values that were inserted while runtime.

For this it is used the calloc, that is a function of the stdlib.h library, of the C programming language. Its objective is to create a vector of dynamic size, that is, defined during the execution of the program. It differs from the malloc function, also from C, because in addition to initializing the memory spaces, it also assigns the value 0 (zero) to each one. It is useful, because in C when a variable is declared, the space in the memory map used by it probably contains some garbage value.

Code:

#include <stdio.h>

#include <stdlib.h>

int main()

{

   int* ptr;

   int n, i;

   n = 15;

   ptr = (int*)calloc(n, sizeof(int));

   if (ptr == NULL) {

       printf("\n Memory is not allocated");

       exit(0);

   }

   else {

       printf("\n Memory allocated");

       for (i = 0; i < n; i++) {

printf("\n Input value in the array at position %d: ",i);

scanf("%d",&ptr[i]);

       }

      printf("\n The elements of the array are: ");

       for (i = 0; i < n; i++) {

           printf("%d, ", ptr[i]);

       }

free(ptr);

   }

return 0;

}

Body mass index is a measurement based on a person's weight and height. The BMI is calculated by dividing the body weight by the square of the size, and it is expressed in kilograms per square meter (kg/m2) since weight is measured in kilograms and height is measured in meters.

Body Mass Index (BMI) is calculated by dividing a person's weight in kilograms (or pounds) by their size in meters squared (or feet). People who are exceptionally muscular may have a high BMI because muscle weighs more than fat.

When you want to add information to a document, the operating system assigns the file its name, location, and size.

An operating system (OS) is the program that manages all of the other application programs in a computer after being loaded into the computer by a boot program. The application programs interact with the operating system by requesting services via a predefined application program interface (API).

The file's name, location, and size are determined by the operating system. When you add information to a word-processing document, one of the functions of your operating system is to store unsaved work in temporary storage.

Therefore, when you add information to a document, the operating system names locates and sizes the file.

Answer: 3001.

Explanation:

The Server would acknowledge the 3001 information after it receives two packets of data from the personal computer, which is being used to communicate with the web server of the TCP (Transmission Control Protocol) with a window of 6000.

A TCP is the defined standard which is used for establishing and maintaining a network conversation. this is a medium from which applications programs exchange data.

The TCP is explicitly called the Transmission Control Protocol which allows computing devices to communicate and exchange information by sending packets over a network. Hence, the byte of information acknowledged after receiving 2 packets of data is 3001.

The bytes of information acknowledged by the web server can be calculated thus :

Therefore, the bytes of information that would be acknowledged by the web server is 3001.

Answer:

Written in Python:

num = int(input("Number: "))

i = 2

print("The factors of "+str(num)+" are ",end='')

while num > 1:

     if num%i == 0:

           num = num/i

           print(str(i)+" ",end='')

           i = 2

     else:

           i = i + 1

Explanation:

This line prompts user for input

num = int(input("Number: "))

This line initializes divisor, i to 2

i = 2

This line prints the literal in quotes

print("The factors of "+str(num)+" are ",end='')

The following while loop checks for divisor of user input and prints them accordingly

while num > 1:

     if num%i == 0:  This checks for factor

           num = num/i  Integer division

           print(str(i)+" ",end='')  This prints each factor

           i = 2  This resets the divisor back to 2

     else:

           i = i + 1

The program that asks the user for an integer and then prints out all its factors is represented as follows:

x = int(input("please input an integer: "))

for i in range(1, x+1):

  if x%i == 0:

     print(i)

The first line of code ask the user to input the integer number.

Then we loop through the the range of 1 to the inputted integer plus one.

The integers is then divided by the looped numbers . if it has no remainder then it is a factor.

Finally, we print the factors.

#include <iostream>//defining header file

#include <vector>//defining header file

#include <algorithm>//defining header file

#include <iterator>//defining header file

using namespace std;//use namespace

void series_of_letters(vector<char> &d)//defining a method series_of_letters that accept a vector array  

{

char f = *min_element(d.begin(), d.end()); //defining a character array  that holds parameter address

   int k = 0;//defining integer vaiable  

   std::transform(d.begin(), d.end(), d.begin(), [&f, &k](char c) -> char//use namespace that uses transform method  

   {

       return (char)(f + k++);//return transform values

   });  

}

int main() //defining main method

{

   vector<char> x{ 'h', 'a', 'd' };//defining vector array x that holds character value

   series_of_letters(x);//calling series_of_letters method

   std::copy(x.begin(),x.end(),//use namespace to copy and print values

Explanation:

In the above code, a method "series_of_letters" is defined that accepts a vector array in its parameter, it uses a variable "d" that is a reference type, inside the method a char variable "f" is defined that uses the "min_element" method for holds ita value and use the transform method to convert its value.

Inside the main method, a vector array "x" is defined that holds character value, which is passed into the "series_of_letters" to call the method and it also uses the namespace to print its values.
