...I died a little inside, to be honest.

A few things to consider

• Declare variables at local scope, not global
• Don't put function bodies and variable declarations in header files. Use headers as 'maps' to access functions/variables across files etc
• Lines like if(a == "y") make me want to shoot myself. Even if the operators are overriden for std::string, it's fucking terrible (s/overridden/obfuscated/)
• You should probably do something simple like this in C, getting used to using arrays and string functions. It'll definitely help you later on.
• Get used to the basic errors, and when dealing with compiler errors, work your way down from the top of the list
• Learn some basic naming conventions/notations. CamelCase for functions, alternativeCamelCase for varibles, myType_t for typedef's, m_pObject hungarian notation for class members, etc

In this case, you have two variables of type std::string, named 'restart' (One in variables.h, one in functions.h)

Ah, I hate it when people say 'C++ is best language yo, learn it gogogo', because it will often bring about bad practices. Seen it time and time again.
Start basic, perfect your basic skills, then branch out into concepts like C++ classes, templates, etc if you really must. I urge you to learn C before using (technical) C++ constructs. It'll make you a lot better in the long run if you have a core understanding of things at a lower level (Even branch into assembly later on)

Just stop it guys..

The fact is that Razor is kinda correct in what he is saying... you can't really say that your way of doing is better to you, because probably you never tried the methods he is actually telling you to do (names).

Plus, if you start doing it in the correct way while you are still at the start, it will save you problems at the future...

just my opinion.. if you don't want criticism about your work, either good or bad.. just don't post it ;s don't you think?
