The document is a practical file for an object-oriented programming course using C++, detailing various programs including arithmetic operations, number checking, and class-based calculations. It includes a table of contents with programs demonstrating fundamental concepts such as inheritance, operator overloading, and data encapsulation. The author expresses gratitude towards their teacher, peers, and family for their support in completing the file.

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.
