Calculate Mean of the array

Write a program to Calculate the Mean of the array.

Mean: It is defined as the sum of terms divisible by the number of terms.

Formula: Sum of terms/number of terms

Example:

Input:  arr[]={4,5,3,2,6,7}
Output: Mean of array is 4.500000

C Program

#include <stdio.h>
int main()
{
    int arr[] = {4, 5, 3, 2, 6, 7};
    //find the lenth of array
    int n = sizeof(arr) / sizeof(arr[0]);
    int sum = 0;
    //find sum of array
    for (int i = 0; i < n; i++)
    {
        sum = sum + arr[i];
    }
    float mean = (float)sum / n;
    printf("Mean of array is %f", mean);
}
