Pure Virtual Functions
An abstract class is one, which is used just for deriving some other classes. No object of this class is declared and used in the program. Likewise, there are pure virtual functions which themselves won't be used. Consider the above example with some changes.
class Shape
{
public :
virtual void print() = 0; // Pure virtual
function
};
class Triangle : public Shape
void print()
cout << " I am a Triangle " << endl;
}
class Circle : public Shape
cout << " I am a Circle " << endl;
void main()
Shape S;
Triangle T;
Circle C;
Shape *ptr;
ptr = &T;
ptr -> print();
ptr = &C;
