A pointer is a variable whose value is the address to another variable. Pointers are most commonly used to dynamically allocate memory off of the heap instead of defining all of your variables at compile-time.
It is a pointer which is pointing to present object with which the memberfunction is called in c++ language.

Let's suppose, you wanted to ask:Why thisis used as a pointer in C++ language? Because it is a pointer to the 'current object'.
You can add a point in C/C++. The legal operations on a pointer are that you can 1.) add a constant, 2.) subtract a constant, and 3.) subtract two pointers that refer to the same array. Anything else is meaningless.
Because of pointers and that all arrays are really pointers. A pointer something like *pointer can also be written as pointer[0] and *(pointer + 1) can also be written as pointer[1]

A pointer is a programming language data type whose value refers directly to (or "points to") another value stored elsewhere in the computer memory using its address.
