help with sorting of array and median!

[Cali_engr]

I have to write a code that uses functions

I have to calculate the median of an array that is inputted by the user,
therefore I have to design a function that sorts the numbers.

So in my median function i need to call on the sort function to get the numbers in order than to determine the median from there to give back to the MAIN program...


I dont even know where to start any help?

this is what I have so far
from the median function and the sort function i am making for my code


+++++

#include <stdio.h>
#include <math.h>

double median(double a[], int n);
void sort(double a[], int n);

int main (void)
{
     int i, w;
     med;


     printf("Enter the number of elements in the array: ");
     scanf("%d", &w);

     double a[w];

     for(i=0; i <w; i++)
         {
             printf("Enter element %d: ", i);
             scanf("%lf", &a[i]);
          }

      med = median(a,w);

      printf("The median is: %.2f", med);
 

      return 0;
}

double median(double a[], int n)
{
    int i=0;
    for(i=0; i<n; i++)
         {
             b[i] = a[i];
          }

     return median;

}


void sort(double a[], int n)
{
         int middle;
}

AFTER you have sorted your array median will be (if I remember correctly):

double median(double* arr, size_t size)
{
   return arr[size/2];
}

so now you only need to sort array.

there is qsort standard function that could help with this task
