C++ Program to Calculate Average of Array Elements

In this program, the user is ask to enter 5 integer elements that will save in array arr. Then we calculate the sum and average of these number display it on console.

Source Code

#include<iostream>
using namespace std;

int main()
{
    int arr[5], i, sum = 0;
    double avg;

    cout<<"Enter 5 array students\n";
    /* Input marks of 10 students */
    for(i=0; i<5; i++)
        cin>>arr[i];

    /* Logic to calculate sum and average*/
    for(i=0; i<5; i++)
    {
        sum = sum + arr[i];
    }
    avg = sum / 5;

    /* Print sum */
    cout<<"\nSum = "<<sum;
    cout<<"\nAverage = "<<avg;
    return 0;
}

Output

Enter 5 array students
4 2 5 8 6

Sum = 25
Average = 5
