While running drafts of mario.c in pset 1 I will at times run a program that has an unintended infinite loop. Is there keystroke combination that I can use to stop the loop and return to the blinking command line prompt?

Yes. To force-exit a running program, press Ctrl + C from your keyboard!

    There are also a few more *nix keystroke combinations worth being aware of; see here and here for more information. Ctrl + D is a particular "gotcha" for those unused to it!
