The document outlines programming problems related to various object-oriented programming concepts like classes, constructors, destructors, inheritance, polymorphism, templates, and file handling. For each concept, 2-3 programming problems are listed to practice the concept. The programming problems involve writing classes to model real-world entities, defining member functions, using inheritance for code reuse, operator overloading, virtual functions, templates, and reading/writing data to files. Solving these problems will help learn and reinforce object-oriented programming fundamentals.

1. CLASSES
 Creating Objects:
Program#01:
Write a program that declares a class with one integer data member and two
member functions in() and out() to input and output data in data member.

2. Program#02:
Write a class Marks with three data members to store three marks. Write
three member functions
1)in() to input marks,
2)sum() to calculate and return the sum and
3) avg() to calculate and return the average marks

4.  Defining Member Functions Outside Class:
Program#01:
Write a program that declares a class with one integer data member and two
member functions in() and out() to input and output data in data member.

5. Program#02:
Write a class Array that contains an array of integers to store five values. It
also contains the following member functions:
1. The fill() function is used to fill the array with the values from the user.
2. The display() function is used to display values of array.
3. The max() function shows the maximum value in the array.
4. The min() function shows the minimum value in the array.
NOTE: All member function should be defined outside the class.

constructor with no parameter initializes both data members to 0. a member
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.

17. STATIC DATA MEMBER
 Static Data Members:
Program#1:
Write a program that counts the number of objects created of a particular
class.

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

19. FRIEND FUNCTIONS
 Friend Functions:
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 +.
