Sooner or later (and always sooner than expected), you will do something wrong in your code and the result will be a sudden, brutal, impolite crash of your application.

This article will show you how to debug the application with a command line debugger. I know it's easier to use an IDE and I might add a dedicated article on debugging with CodeLite. But you don't always have an IDE available. Your favorite IDE might not be ported to some obscure platform you want your game to run on. gdb is always a useful addition in any C/C++ developer's swiss army knife.
