c字符串的qsort函数用法

#include <stdio.h> #include <stdlib.h> #include <string.h> using namespace std; #define LINE 100 int bsearch_cmp1(const void* elem1, const void* elem2){ return strcmp((char *)elem1, (char *)elem2); } int main(){ char bs[][LINE] = { "dfafd", "fdafdafda", "daefda", "derew", "fewewe", "fdaere" }; qsort(bs, sizeof(bs)/sizeof(bs[0]), sizeof(bs[0]), bsearch_cmp1); //cout<<sizeof(bs)<<" "<<sizeof(bs[0])<<" "<<sizeof(bs)/sizeof(bs[0])<<endl; for(unsigned int i = 0; i < sizeof(bs)/sizeof(bs[0]); i++){ printf("%s/n", bs[i]); } }
