Description

To find the average of elements present in the array,
Calculate the sum of elements of array, divide the sum by
total number of elements present in the array.
To get the appropriate result, use typecasting.

C/C++

/*C program to find average of elements*/
// Save it as AverageOfElements.c

#include<stdio.h>
int main(){
    int i,n;

    printf("Enter the size of array : ");
    scanf("%d",&n);

    float arr[n];

    printf("Enter the elements of array : ");
    for(i=0;i<n;i++){
        scanf("%f",&arr[i]);
    }

    float sum = 0.0;

    for(i=0;i<n;i++) {
        sum += arr[i];
    }
    printf("Sum of elements : %.2f", sum);

    float average = sum/n;

    printf("\nThe average of elements : %.2f", average);

    return 0;
}
