Or this:
http://www.sfml-dev.org/documentation/1.6/structsf_1_1Event_1_1KeyEvent.htm
I don't know anything about openGL though.
But in allegro I use a std::string and concatenate every character when the user presses a key (first you have to make sure the user didn't press the Enter key, backspace, Escape, etc)
Notice that TTF fonts have different widths on every character so a simple multiplication won't work.

I know this thread is a little bit old (133 days), but I have a question:
Do you have some sites where I could learn how to make a simple (and i mean SIMPLE SIMPLE) compiler in C/C++?
Or creating an .exe file that does something. (simple console output would be a good start)
EDIT: I don't want to compile C++ code, I want to create a compiler for my own (LITTLE) scripting language.
Scheme is one of the easiest to implement languages out there. To create a full fledged language, you will need to learn to use one of several DSL specific toolkits (lex comes to mind), how to implement, build, and traverse AST trees, and how to atomically represent computations with a bijection into the actual computation space. These are the primitives for building your own language. (By compiler I assume you mean an interpretor, as the output produced by a compiler is not executable.)
but I just wanted to know if there's a way to create .exe files with C/C++.....
And it's not that i want to start a big project, I'm just curious.
