Return from void functions in C++
Void functions are “void” due to the fact that they are not supposed to return values. True, but not completely. We cannot return values but there is something we can surely return from void functions. Some of cases are listed below.
A void function can do return
We can simply write return statement in a void fun(). In-fact it is considered a good practice (for readability of code) to write return; statement to indicate end of function.
A void fun() can return another void function
The void function has returned a void() !!!
The above code explains how void() can actually be useful to return void functions without giving error.
A void() can return a void value.
A void() cannot return a value that can be used. But it can return a value which is void without giving an error.
