There is a third option:
You could comment out the "main" main() function to write a small "test" main() by putting block comments arround one of the functions...
/*
int main()
{
... code ...
}
*/
... or by using the Code::Blocks shortcut of highlighting the function and hitting Ctrl-Shift-C (or Ctrl-Shift-X to uncomment).
(Off-topic: oBFusCATed, nice post count :)... I wanted to say right when it turned, but I missed.)
