Program to sort the given numbers using quick sort

Program:

#include<stdio.h>
#include<conio.h>
#include<values.h>
int a[10] ;
void main()
{
    int i, n;
    void qsort(int, int);
    clrscr();
    printf("Enter the limit : ");
    scanf("%d", &n);
    printf("\nEnter the elements :\n\n");
    for(i = 0; i < n; i++)
    scanf("%d", &a[i]);
    a[i] = MAXINT;
    qsort(0, n - 1);
    printf("\nThe sorted elements are :\n\n");
    for(i = 0; i < n; i++)
    printf("%d\t", a[i]);
    getch() ;
}
void qsort(int left, int right)
    {
    int i, j, t, v;
    if(left < right)
    {
        i = left + 1;
        j = right;
        v = left;
        for( ; ; )
        {
            while(a[v] >= a[i])
            i++;
            while(a[v] < a[j])
            j--;
            if(i < j)
            {
                t = a[i];
                a[i] = a[j];
                a[j] = t;
            }
            else
            break;
        }
        t = a[v];
        a[v] = a[j];
        a[j] = t;
        qsort(left, j - 1);
        qsort(j + 1, right);
    }
    return;
}

Output:

Enter the limit : 5
Enter the elements :
20 40 30 50 10
The sorted elements are :
10 20 30 40 50
