自己写了 有错误 能不能 帮我修改下
#include <stdio.h>

void quicksort (int *a, int *low, int *high);
int split (int *a, int *low, int *high);

#define N 10

int main(void)
{
    int *p;
    int a[N];
   
    for (p = a; p < a + N; p++)
    {
        scanf ("%d", p);
    }
   
    p = a;
    quicksort (p, &a[0], &a[N - 1]);
   
    for (p = a; p < a + N; p++)
    {
        printf ("%-3d", *p);
    }
   
    return 0;
}

void quicksort (int *a, int *low, int *high)
{
    int *middle;
   
    if (low >= high) return;
    middle = split (a, low, high);
    quicksort (a, low, middle - 1);
    quicksort (a, middle + 1, high);
}

int split (int *a, int *low, int *high)
{
    int part = *low;
   
    for (;;)
    {
        while (low < high && part <= *high)
        high--;
        if (low >= high) break;
        *low++ = *high;
        
        while (low < high && *low <= part)
        low++;
        if (low >= high) break;
        *high-- = *low;
    }
   
    *high = part;
   
    return high;
}
