function get() inputs the values and function show() display the values. It has
the member function add() that takes an object of type Travel to add the
kilometers and hours of calling object and the parameter.

15.  Returning Objects from Member Functions:
Program#1:
Write a class Travel that has the attributes of kilometers and hours. A
constructor with no parameter initializes both data members to 0.

16. Program#2:
Write a class Travel that has the attributes of kilometers and hours. A
constructor with no parameter initializes both data members to 0.

class.

18. Program#2:
Write a program that clears concept of static member function.

Program#1:
Write a program that demonstrate the use of Friend Function.

20. FRIEND CLASSES
 Friend Classes:
Program#1:
Write a program that demonstrates the use of Friend Classes.

21. STATIC FUNCTIONS
 Static Functions:
Program#1:
Write a program that demonstrate the use of Static Functions
.

22. Program#2:
Write a program that counts the number of objects created for a particular
class. The program must be able to display the results even if no object is
created so far.

23. OPERATOR OVERLOADING
 Operator Overloading:
Program#1:
Write a program that overloads increment operator to work with user-defined
objects.

24. Program#2:
Write a program that overloads binary addition operator +.

which is initialized to zero when an object is created. It also has a member
functions forward() which increments the value of position by 1 and show()
function to display the value of position.Move2 class is a derived class and has
a member function backward() to decrement the value of position by 1.
