I'm just going to assume that you were taught to write pre-standard C++ (which contains void main, conio.h, getch, etc) and just in case it is true: https://www.sololearn.com/Discuss/288609/?ref=app

It's just how C++ relays the exit status to your OS. 0 means it exited successfully, and 1 means it failed. This is good for being able to properly display errors as the program terminates.
