Compiler Suggestion For Newbie Programmer

Hey everyone I've begun learn coding through Codeacademy, and I was wondering if anyone could recommend any compilers that are easy to start out in. At this time, I'm mostly just looking for somewhere I can apply what I learn in a different environment outside of what the site has, mostly to just experiment and get more comfortable outside of the exercises that the site provides.

Also, free would be preferred since this is a hobby atm, and not a career move. Thank you!
