Answer 1

Your piping to cout is the wrong way:
cout << key

Please! Indent correctly, to make your code readable

Answer 2

Change line 12 to the following and it will work:

cout << bol;

Answer 3

You have to include
#include <string>
to be able to compare strings.

Answer 4

#include <string> is part #include <iostream> , why include it then?
sorry for my bad English

Answer 5

There some more features in this header.

Answer 6

Okay, I understand the problem. Cout does not output the values of variables of type boolean.

Answer 7

cout >> bol is wrong, you have to use << with cout
