整数的比较函数实现好像有问题 #13

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
int int_cmp(void* a, void* b)
{
    return (int)a - (int)b;
}
是把a和b的地址强转成int型后比较，并非比较a,b实际的值

应该是
int int_cmp(void* a, void* b)
{
    return *(int *)a - *(int *)b;
}

谢谢。这个没错：a/b并不是指针，是一个整数，所以不能转��
�成指针再取内容。
