8 – Best C program to find average of array

#include<stdio.h>

float avgfun(float a[],float len)
{
    float rsl=0;
    int i;
    for(i=0;i<len;i++)
    {
        rsl+=a[i];
    }
    rsl/=len;
    return rsl;
}
//itvoyagers.in
int main()
{
    float avg,nums[] = {1,2,3,4,5,6};
    float l = sizeof(nums)/sizeof(float);
    avg = avgfun(nums,l);
    printf("Average of array is %.2f",avg);
