People use void main() /*empty parens ()*/
I have been taught to write void main(void)
Any ideas what the difference is?

I’m not sure what the standards are nowadays, but in traditional ANSI C, using empty parentheses indicates that the function can take any number of arguments. Declaring a
voidparameter on the other hand indicates that the function only takes zero arguments. In this case (and many others), it really doesn’t matter too much.If you want to be strict though, it’s probably best to define the
voidparameter. Of course, themainfunction can also be defined asint main(int argc, const char* argv[])– which is perfectly valid, but often unnecessary if you don’t care about arguments.
