error: ISO C++ forbids comparison between pointer and integer if(s != "b"){
This is a common error in C++, and it's easy to get wrong. It's not just a matter of forgetting to use them != operator, but also of forgetting that there's a null pointer exception that can throw an exception anywhere in the program (and it will be caught by whoever called the function).

The reason for this is that pointers are not integers. You can't compare them directly with == or != operators; you have to compare them indirectly with some function that returns non-zero if it has more than one argument and zero otherwise. The standard library provides such functions for most types, but not for pointers.
