Program – Find the average of n numbers

#include <stdio.h>
void main ()
{
    int n, i;
    float list [100], avg;
    float average (float [], int);
    /*function declaration*/
    clrscr (); 
    printf (“\nenter the number of numbers:”)
    scanf (“%d”, &n);
    printf (“\nenter the numbers\n”);
    for (i = 0; i<n; i ++)
    scanf (“%f”, &list[i]);
    avg = average (list, n);
    printf (“\naverage = %9.2f”, avg);
    getch ();
}
float average (float x [], int a)
{
    int p;
    float sum = 0.0, aver;
    for (p=0;p<a;p++
    sum = sum + x [p];
    aver = sum/(float)a;
    return (aver);
}
