what is the purpose of return(0)?

[wart101]

please?

[Ancient Dragon]

as used in function main() it returns a value to the operating system and can be used by calling programs. Historically, 0 means successful completion of the program (no errors), while other return values are an error number -- the program is free to use whatever number (positive or negative) it whishes.
