第 9、10 和 13 行中的错误“未找到采用 'std:istream' 类型的左侧操作数的运算符(或没有可接受的转换'”
#include <stdafx.h>  // I should have put #include "stdafx.h" instead
#include <iostream>  // My mistake was I didn't #include <string>
using namespace std;
    int main()
{
    cout << "This is the left step bitwise operation\n";
    string x;
    cin >> x;  // line 9
    cout << "You typed" << x;  //line 10
    string y;
    cout << "Enter second number please!"; 
    cin >> y; // line 13
    cin.get();
    return 0;
} // line 
我的模糊猜测是我没有#include 某些东西
