More info than that is needed.

What platform are you on?

Do you have core dumps enabled/disabled?

If you have it enabled...where does it put them?

And yes, core dumps are potentially useful for debugging.

However, given you're asking that question, and getting core 
dumps, then it might be easier for you to use the -g option when 
you compile, and then run your executable (or a.out) through a 
debugger:
