Ok, I am sure this has already been solved somewhere, but I haven't found it yet. Anyway, I am writing a program for class and I keep getting this 'error' when I run it. I am using kate/gedit as my text editor, coding in C++, and compiling with g++. when I run my program (which is very small, [hangman]) i get: 'Segmentation fault (core dumped)'. So,

1. What does that mean?
2. Where does it come from/ where is the core being 'dumped'?
3. How do I fix that problem? or can I even fix it?

Thank you in advance. I'm kind of a novice Linux user as I am still learning a lot of things.
