Why in this app return 0 is used

Question

I have learnt that to use getch () as ending bt here return 0 is user can u help me out

Answer 1

the return zero is just to see if your program executed correctly. on some compilers, after your program runs you will see "exited with status 0" or something like that. you should create a program that runs but doesn't work properly you will see your program will return probably a negative number

Becus we use
int main() function
so we must
return 0;
I never use void main becus I'm always reach error
