STL中List 的sort 比较 用法示例

#include <string>#include <list>#include <algorithm>#include <iostream>using namespace std;bool op(string str1, string str2){ return str1.length() < str2.length();}int main(int argc, char* argv[]) { list <string> list_story; list_story.push_back("the"); list_story.push_back("quick"); list_story.push_back("red"); list_story.push_back("fox"); list_story.push_back("jumps"); list_story.push_back("over"); list_story.push_back("the"); list_story.push_back("slow"); list_story.push_back("red"); list_story.push_back("turtle"); list_story.sort(op); for(list<string>::iterator i = list_story.begin(); i != list_story.end(); i++) { cout << *i << endl; }}
