看附图，我对代码
#include <iostream>
#include <string>
#include <vector>

using namespace std;

using std::vector;
using std::string;
using std::cin;
using std::cout;
using std::endl;

int main()
{
    string word;
    vector<string> text;
    while(cin>>word)
    {
        text.push_back(word);
   
    }
    for(vector<string>::iterator i=text.begin(); i != text.end(); ++i)
        cout<<(*i)<<endl;
   
    cout<<endl;  

    return 0;
}进程编译，明明在上面提示了很多歌警告
却在最后一行显示 test.exe - 0 error(s), 0 warning(s)？

Cpp1.exe - 0 error(s), 4 warning(s)

0 error(s), 4 warning(s)
VC哪里错了？

我的编译器 最后一行是  test.exe - 0 error(s), 0 warning(s)（参见附图 ）

请问这个程序为什么会有warning呢？我刚学到这里，编了一个相同的程序，也有4个warning，不知道是为什么~~

刚才把 string类型改成内建类型就没有警告了
不知道是不是因为容器一般作用于 非内建类

弱问~~~什么是内建类型~~
