What is the difference between no parameter and the void parameter in C++?

Question

I've recently switched from Java to learning C++, I'm a newbie to this language so I need your help :)

What's the difference?

void method(void) {

}

and

void method() {

}

Many thanks!

In C++, there's no difference -- they both mean a function that takes zero arguments.

In C, () means a function that takes any number of arguments, while (void) means a function that takes zero arguments.

None. There was a difference in C (void means no parameters and nothing means an unknown number of parameters) but not in C++; they are the same.

C++ is the exact same, however in C it means a function that takes any # of arguments. It is really just a stylistic matter that is up to you.
