- 2. Acknowledgemen t I have takenefforts 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. Place: Date: P a g e 2

- 7. 32. Program todemonstrate 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. P a g e 6
