Where does "this" pointer exist?

Question

It definitely isnt in the class object because sizeof(classobj) doesnt include "this" size

Take for eg:

Class X{
Public:
int getData(). {
return this->data;
}

int data;
};

Int main()
{
X obj;
Cout << sizeof( obj); // prints 4
}

It prints 4 because sizeof(obj) = sizeof(obj.data) = 4

Why does sizeof(obj) not include the this pointer size?

Answer 1

this is just a pointer which comes into picture when u create an object of the class. then only u can get the this pointer which points to class object itself.

u can't access this variable in static methods of class as static methods are not created when objects are created, instead static methods are part of class not the object.
