A function can still useful even if you don't pass any arguments to it and the function dosen't return any value back.

Question

Is this statement true ?

Answer 1

The statement is true.

Answer 2

depends on the programming paradigm. For functional languages (strictly pure functions) the whole point of a function is it’s return value. A function with no return value is useless. In other paradigms, e.g. OOP and imperative programming paradigms a function without arguments and return values can be very useful. For example, someObject.destroy(), or invokeGarbageCollector().

Answer 3

Jason Stone Indeed... you are correct. However, I'm assuming the context is imperative since the question is tagged with "c".

Answer 4

David Carroll I did notice that but only right after I posted my comment. And a little more in depth information (probably) won’t hurt.
