discussion, it is mentioned that
In composition, you can change the member objects @ runtime, to dynamically change the behaviour of the program.
Inheritance does not have this flexibility since compiler must place compile time restrictions on classes created with inheritance.
I doesn't understand this concept.
Can any one give an example code illustration this.
