Lab Exercises
3.2 Write a program create a class ‘simpleobject‘. Using constructor display
the message.
3.3 Write a program for the following
1. Example for call by value.
2. Example for call by reference.
3.4 Write a program to give the example for ‘this’ operator. And also use the
‘this’ keyword as return statement.
Lab – 4 (2 Hrs Real Time)
4.1 Write a program to demonstrate static variables, methods, and blocks.
4.2 Write a program for reuse class. For this program use the above ‘room
class’ program.
4.3 Create class named as ‘a’ and create a sub class ‘b’. Which is extends from
class ‘a’. And use these classes in ‘inherit’ class.
4.4 Write a program to give the example for method overriding concepts.
4.5 Write a program to give the example for ‘super’ keyword.
Lab – 5 (2 Hrs Real Time)
5.1 Write a program to create a class named shape. In this class we have three
sub classes circle, triangle and square each class has two member function
named draw () and erase (). Create these using polymorphism concepts.
5.2 Write a program to give a simple example for abstract class.
5.3 Write a program suppose, it is required to build a project consisting of a
number of classes, possibly using a large number of programmers. It is
necessary to make sure that every class from which all other classes in the
project will be inherited. Since any new classes in the project must inherit
from the base class, programmers are not free to create a different
interface. Therefore, it can be guaranteed that all the classes in the project
will respond to the same debugging commands.
