回调函数的使用

#include <stdio.h>
int callBackCompare(int a,int b)
{
    return a<b?0:1;
}
void selectSort(int *p, int n,int(*pf)(int,int))
{
    for(int i=0; i<n-1 ;i ++)
    {
        for(int j=i+1; j<n; j++)
        {
            if(pf(p[i],p[j]))
            {
                p[i] = p[i]^p[j];
                p[j] = p[i]^p[j];
                p[i] = p[i]^p[j];
            }
        }
    }
}
int main(void)
{
    int arr[10] = {6,5,4,3,2,1,7,8,9,0};
    selectSort(arr,10,callBackCompare);
    for(int i=0; i<10; i++)
    {
        printf("%d\n",arr[i]);
    }
    return 0;
}
