1. this Pointer

• When calling a member function on an object, the compiler implicitly passes the object's address as an argument.

• The compiler internally declares a pointer inside the member function to store this address.

• This pointer is called the this pointer.

• It is a constant pointer (i.e., it cannot change which object it points to).

• General syntax:

  ClassName *const this;
  

2. Types of Member Functions

Member functions inside a class are classified into:

1. Constructor - Used to initialize an object.
2. Destructor - Used to release resources.
3. Mutator - Modifies the object's state (also called setter function).
