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;

}
