I have taken efforts in this practical file. I am highly indebted
to the C++ programming teacher for her guidance and
constant supervision as well as for providing necessary
information regarding the programs and also for her support in
completing the practical file.
I would like to express my gratitude towards my parents for
their kind co-operation and encouragement which helped me
in the completion of this practical file.
My thanks and appreciations also go to my classmates in
developing the practical file and to the people who have
willingly helped me out with their abilities.

constructor member function to initialize
an object during its creation.

member function can access private data
members of a class.

inheritance.
31. Program to implement hierarchical
inheritance.
P a g e 5

32. Program to demonstrate multiple
inheritance in which a class is derived
publicly from both the base classes.
33. Program to understand hybrid
inheritance, consider an example of
calculating the result of a student on the
basis of marks obtained in internal and
external examination.
34. Program to calculate the result of the
student using private inheritance.
35. Program to demonstrate the use of
protected members.
36. Program to illustrate the concept of
overriding member functions.
37. Program to maintain student information
by creating a composite class having one
of its data member as an object of
another predefined class.
