Write a complete C++ program that do following. Read a positive integer from the user with proper prompt. Assume that this user is nice and he/she would not start the integer with digit 0. Create a size 10 array as counters for digits 0 - 9 Use a while loop for processing

The cpp program for the given scenario is shown below.

#include <stdio.h>

#include <iostream>

using namespace std;

int main()

{

//variable for while loop

   int n=0;

   //size of array declared

   int size=10;

   //integer array declared

   int num[size];

   //user enters elements for the array inside while loop

   while(n<size)

   {

       std::cout << "Enter a positive number: ";

       cin>>num[n];

n++;

   }

   std::cout << "Thanks for entering the numbers. Program ends." << std::endl;

   return 0;

}

Explanation:

1. The integer variable, size, is declared and initialized to hold the size of the array.

int size=10;

2. Another integer variable, n, is declared to be used in the while loop.

int n=0;

3. An integer array, num, is declared having the capacity of integer variable, size.

int num[size];

4. Inside the while loop, the user is prompted to enter a positive number.

std::cout << "Enter a positive number: ";

5. The user-entered number is assigned directly to the array.

cin>>num[n]

6. After input is taken, the variable n is incremented by 1.

n++;

7. The while loop executes over variable n for the range of values from 0 to size-1,  i.e., until the array is filled. The first index of the array is 0 and increments henceforth. The variable is declared outside the loop unlike the for loop.

while(n<size)

8. In this program, all the code is written inside main().

9. Since cpp is not a purely object-oriented language, it is not mandatory to write the code inside the class for a simple program like this.

10. The program ends with a message for the user.

std::cout << "Thanks for entering the numbers. Program ends." << std::endl;

11. The return statement indicates the end of main() method.

return 0;

12. The output of the program is attached as an image.

13. The program can be tested for any value of variable size.
