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.

its pointer created for high safety that cant be find by anyone.
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'.
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]
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.
pointer: to access data by address reference: there is no reference in C language

No. In computer programming, a class is a data type while a pointer is a variable that can store a memory address.
