What is "return 0;" form?

Question

Why do i need to put return 0; ???

Answer 1

Short answer: just put it and forget about it.

Long answer: the value returned by the program can be used if it was launched by another program. A return value of 0 means no error, and a non-zero return value means any error of your choosing. You can then do things differently in the host program depending on that return value. Needless to say, that feature is seldom used.
