摘要：六类qsort排序方法前一段时间做题觉得qsort函数很好用，但有时不太会用比如按结构体一级排序、二级排序、字符串排序等，故通过查资料将其整理一番。以下是其具体分类及用法(若无具体说明是以降序排列)：1、对一维数组排序：（Element_type是一位数组中存放的数据类型，可以是char, int, float, double, etc）int Comp(const void *p1,const void *p2){return *((Element_type *)p2) > *((Element_type *)p1) ? 1 : -1;}int main(){Element_type
