What is type of “this” pointer? Explain when it is get created?

Question

What is the point of declaring Pointer of different types (eg. integer,float,char) as we all know pointer takes 4 bytes of space regardless which type of pointer it is and only contains address?

Answer 1

The ‘this’ pointer is passed as a hidden argument to all nonstatic member function calls and is available as a local variable within the body of all nonstatic functions. ‘this’ pointer is a constant pointer that holds the memory address of the current object. ‘this’ pointer is not available in static member functions as static member functions can be called without any object (with class name).

It is a constant pointer type. It gets created when a non-static member function of a class is called.
