return will set the value of the return to the variable that called it. for example, let's say we have this: int i = setITo15 (); then in an integer function setITo15 we have this declaration: into setITo15 () {return 15;} when this function finishes the varable that called it, i, will be set to 15. if you're referring to return 0 I'm int main it simply returns 0 once the program reaches the end of its code, essentially saying that I did everything I was told to do. of the program stopped prematurely it would return a different code like -156725 or something like that. in this case it's just a difference between executing the program completely or not
