what is the value stored in void in C++

Question

What is the value that is stored in void()? Basically it is used before a function which doesnot return anything. But does simply void holds any value?

That's one of the best kept C++ secrets. The value is `42`. (this is a joke, in case it wasn't clear) :) — Luchian Grigore, Oct 15 '14 at 14:47

It really was a joke. — Rudy Velthuis, Oct 15 '14 at 15:02

Void is an incomplete type which, by definition, can't be an lvalue. That means it can't get assigned a value.

So it also can't hold any value.

The use of void for a return value means simply that there is nothing returned. So, there is no value, because there is just nothing at all.
