C++ Pointer

C++ Pointer

Pointer

Uses of this

• The this pointer is useful when operators are overloaded.

• The this pointer is useful when the member function tries to find out the address of the object of which it is a member.

class Where
{
char array[10];
public:
void reveal ( ) { cout<<”\nMy objects address is “<<this<<endl; }
};
void main ( )
{
Where w1, w2, w3;
w1.reveal ( );
w2.reveal ( );
w3.reveal ( );
}

Restrictions

• First, friend functions are not members of a class and, therefore, are not passed a this pointer.

• Second, static member functions do not have a this pointer.
