Introduction to Polymorphism
Is the ability to take more than one form. For example an operation may behave differently indifferent instances. The behaviour depends on the types of data used in the operation. This is similar to a word having several different meanings depending on context.
To illustrate this concept consider an example of drawing a specific shape. It is shown in fig above, in which a shape can be drawn in the form of either a circle, a box or triangle.
To extend the example shape consider the various 2D shapes defining the class shape 2D as shown in fig below.
This example has a four level hierarchy with generalizations. Various classes used are:
1. Elliptical shape and polygon which inherit from shape 2D.
2. Simple polygon and arbitrary polygon which inherit from polygon.
3. Circle and ellipse which inherit from elliptical shape.
4. Rectangle and regular polygon which inherit from simple polygon.
Shapes 2D is the ultimate super class of the hierarchy. All its operation and methods are inherited by each of other subclasses. Shapes 2 Modify the shape. Following are the outcomes of its operations:
The class which inherit these operations take advantage of properties unique to its class. That means that every operation will perform a function which is specific to that class only. For example the rotate function perform rotation with the degrees specified for every specified shapes. For circle it does absolutely nothing and returns immediately.
C programming simulates polymorphism using void pointers and doing a considerable amount of type casting. While the simulation is possible we cant use a structure hidden within a void pointer first casting it to be a pointer to a given structure. So,
