" 'void main() ' vs 'int main()' " and " 'getch();' vs 'return.0' "

getch() - is only borland specific.

getch() is not borland specific... Its available where ever it is defined...

You can use it in VC++ by including conio.h or on pretty much any UNIX machine by including... curses.h or ncurses.h

all it does is wait for a user to press <enter>

Actually it retrieves a character from standard input (STDIN) without echo'ing it... although waiting for user to press enter is one use of it.
