Question

Error in line 9, 10 and 13
“no operator found which takes a left-hand operand of type ‘std:istream’ (or there is no acceptable conversion'”

#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 

My vague guess is that I didn’t #include something

Answer 1

You forgot to #include <string>. Your code relies on that when you input a string, as well as when you declare it, and when you output it.

#include "stdafx.h"
#include <iostream>
#include <string> <------

I can’t take too much credit for this, so it’s a community wiki.
