In a program, a function call takes a certain amount of time and space (to protect the site) overhead. When we call small functions frequently, the cost of the function calls is relatively large (calling complex functions), so we need the same as

Each member function contains a constant pointer, which we call the this pointer, which points to the object that called the function, whose value is the first address of the object. With this pointer, we can access the object in the function body
