Thread: about stack

Hello,

I am making a program on "stack" data structure and have used classes in them to make the C++ program.


Is it necessary that we should put a return type for "isFull()" and "Isempty()" method?

Also, are "IsFull" and "Isempty" member functions of stack?

Regads,

You certainly should specify the return type, so I assume that you are asking if the return type should be something other than void.

It sounds like they are functions that return a boolean value, so yes, I would expect a return type other than void. That said, it is still possible to have them have void as the return type, but it isn't what I would expect here.

That depends on how you want to design the interface of the class. Depending on what is the core interface you provide, these functions do not necessarily have to be member functions.
