Getting "Segmentation fault (core dumped)"

I use Ubuntu 12.10 as my operating system, and I'm not sure if this is related to that, but that's what I get when I compile my code - No errors, just get that in my terminal.

Line 143
int grades[] = {};
You did not size your array. Size should be 10 I guess.

Line 77, try const int frequencySize = 10;

You should learn gdb. Also compile and test often.
