    int mean(int list[], int size)
    {
        // ...
    }

    int main()
    {
        int a[] = {1, 1, 2, 3, 5, 8, 13};
        // ...
        int m = mean(a, 7);
        return 0;
    }

Do you anything at all in C or you just want some ideas?

#include<iostream>

using namespace std;

double median(double a[], int size)
{
    if(size%2 == 0){
          double lower = a[size/2];
          double upper = a[size/2+1];
          return (lower+upper)/2;
    }
    return a[size/2+1]; 
}

int main()
{
   double a[] = {1,1,2,3,4,8,13};
   double median = find_median(a,7);
   double mean = find_mean(a,7); //think yourself =)
}
