find函数

这个也是直接贴代码吧，比较简单

#include <string>#include <iostream>#include <vector>#include <algorithm>int main(){    std::string str1 = "hello";    std::vector<std::string> svec;    svec.push_back("Hello");    svec.push_back("World");    svec.push_back("Baidu");    svec.push_back("Study");    svec.push_back("Hard");    std::vector<std::string>::iterator iter;    for(iter = svec.begin(); iter != svec.end(); ++ iter)        if(*iter == str1)            break;    iter = find(svec.begin(), svec.end(), str1);    if(iter != svec.end())        std::cout << "Yes" << std::endl;    else        std::cout << "No" << std::endl;    return 0;}
