a) Define the following terms with examples: (i) Abstract data type(ii) Polymorphism(iii) Inheritance(iv) Templates Q3)
Design an EMPLOYEE base class. Define all its possible methods anddata structures. Through inheritance mechanism, create one class namelyMANAGER. Implement its data structure and important methods. Assumethat you are making this design for the purpose of making a salarystatement. Observe the following while designing classes:• Clearly indicate public and private classes• Design constructors in each class and explain its purpose• Identify data structure and methods which can be inherited• Implementation should be in C++ Q4)
Prepare object diagrams showing at least 10 relationships among thefollowing object classes. Include associations, aggregations andgeneralizations. Use qualified associations and show multiplicity balls inyour diagrams. You do not need to show attributes or operations. Useassociation names where needed. As you prepare the diagrams you mayadd additional object classes:School, playground, principal, classroom, book, student, teacher, cafeteria,rest-room, computer, desk, chair, door.
Prepare a data flow diagram for computing the volume and surface areaof a cylinder. Inputs are height and radius of cylinder. Outputs are volumeand surface area. You can use any arbitrary formula for demonstration.

A system for distributed electronic mail over a network is needed. Eachuser of the system should be able to send mail /Tom any computer accountand receive mail on one designated account. There should be provisionsfor answering or forwarding mail, as well as saving messages in files orprinting them. Also users should be able to send messages to severalother users at once through distribution lists. Each computer on the netshould hold any messages destined for computers which are down.
Q10) Write code to implement the following:
