Some people may tell you that its "OK" to use void, because some compilers accept it. although many compilers do not accept it (and will either refuse to compile altogether, or throw out a warning). In some cases, the compiler will accept it, but your program may crash while its trying to exit, if the O/S, or some other program needs to be fed a return value from your program. In some cases, everything will work fine, but you shouldn't count on this. Also - posting code over the internet which uses void main will often get you attention from experienced C/C++ programmers for the wrong reason (They'll likely tell you to change it).

And not just kill you kill you, but kill you with dull things like spoons or really dull butter knives. Don't be a dweeb, int main is where it is at!

Just as long as you understand what int main does & why it works, & when you can actually get away with using void main then I don't see a problem with it.
