Question

Write a program that will get the average of all integers from 1 to 20 using do-while loop.

Answer 1

#include <iostream>


#define SIZE 20


int main()
{
    int sum=0;
    double avg=0;
    int i = 0;
    do
    {
        sum += i;
        i++;
    } while (i <= SIZE);
    avg = (sum / SIZE);
    std::cout << "Average of all integers from 1 to 20 : " << avg << std::endl;

return 0;
}
