Since the return type is int or integer (at the begging of the function), you must return a whole number. Other functions might return a string or other type. This is mentioned in the last 60 seconds of the video if you'd like to review it.

When main returns 0, this means there were no errors found in your program that will prevent building/compiling. When main returns 1, errors have occurred. I would assume 0 is always placed there because it makes more sense to assume the program is written correctly then check for errors.

Full Stack JavaScript Techdegree Graduate 51,574 PointsWhat about void main() ? Is it used in pure C? I know we learned in school in 2003 to use void type on the main function for C++ -> is that still the same practice or did it change?
Thanks for answering.
