"void main()" being taught doesn't make it the right way to define main.
If someone taught you that they shouldn't be teaching C.  main() MUST
return int.  The following are acceptable....

main()
int main()
int main(void)
int main(int argc, char **argv)

Yes, but it MUST always return int.  Period.  Exclamation point!

And you'll do it incorrectly.  "void main()" is not legal C.  It invokes
undefined behavior.  There is no guarantee that the program will work
properly if main is declared void.

I'll say it again just to be sure you heard me.  "main()" must be declared
"int"!!!!!!!!!!!!
