C Programming Example - Calculate Average of Array Elements

C Examples

Use a for loop to iterate through the output elements, sum all the elements to calculate the total, and then divide by the number of elements:

Example 1

#include<stdio.h>
int main()
{
    int array = {1, 2, 3, 4, 5, 6, 7, 8, 9, 0};
    int sum, loop;
    float avg;

    sum = avg = 0;

    for(loop = 0; loop<10; loop++)
    {
        sum = sum + array;
    }

    avg = (float)sum / loop;

    printf("Average is %.2f", avg);

    return 0;
}

Output:

Average is 4.50

User-defined input:

Example 2

#include<stdio.h>
int main()
{
    int n, i;
    float num, sum = 0.0, average;

    printf("Enter number of elements: ");
    scanf("%d", &n);

    while(n>100 || n<= 0)
    {
        printf("Error! Number should be in range of 1 to 100.n");
        printf("Enter again: ");
        scanf("%d", &n);
    }

    for(i = 0; i<n; ++i)
    {
        printf("%d. Enter number: ", i+1);
        scanf("%f", &num);

        sum += num;
    }

    average = sum / n;
    printf("Average = %.2f", average);

    return 0;
}

Output:

Enter number of elements: 4
1. Enter number: 1
2. Enter number: 2
3. Enter number: 4
4. Enter number: 8
Average = 3.75
