void main() /*empty braces()*/
I'm not sure what the standards are nowadays, but in traditional ANSI C, using empty braces idicates that the function can take any number of arguments. Declaring a
void parameter on the other hand indicates that the function only takes zero arguemnts. 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
void parameter. Of course, the
main function can also be defined as
int main(int argc, const char* argv) - which is perfectly valid, but often unnecessary if you don't care about arguments.
