In contrast to C++, in the functional programming language Haskell, the void type denotes the empty type, which has no inhabitants . A function into the void type does not return results, and a side-effectful program with type signature IO Void does not terminate, or crashes. In particular, there are no total functions into the void type.
In C, C++, C#, D, and PHP, void is used to designate a function that does not return anything useful, or a function that accepts no arguments. The unit type in C is conceptually similar to an empty struct, but a struct without members is not allowed in the C language specification (this is allowed in C++).
the return type is int.The program can therefore rely on the method returning a value of type int.Various mechanisms are used for the case where a subroutine does not return any value, e.g., a return type of void is used in some programming languages:
In object-oriented computer programming, a null object is an object with no referenced value or with defined neutral (null) behavior.The null object design pattern, which describes the uses of such objects and their behavior (or lack thereof), was first published as "Void Value" [1] and later in the Pattern Languages of Program Design book series as "Null Object".
