Scenario
Consider that a school "ABC" hired you as a programmer to maintain the record of its Students and Teachers. You need to develop a system in C++ to enter the data and show it as and when required.
Task
Keeping the above scenario in view, you are required to write a C++ program that can display the information of any specific Teacher or Student.
Your solution should contain the following three classes:
-
Person
-
Teacher
-
Student
A Person should be the base class, and Teacher and Student should be its derived classes.
You are required to use the concept of Polymorphism to generate the sample output.
Class Table for the Scenario
| Class | Data Members | Member Functions |
|---|---|---|
| Person | • Name • Age • Gender • Address • Phone | • Default Constructor • Setter and getter functions for all data members • A function to save information of a person • A function to display information of a person |
| Teacher | • Qualification • Salary | • Default Constructor • Setter and getter functions for all data members • A function to save information of a Teacher • A function to display information of a Teacher |
| Student | • Previous Education • Obtained marks • Total Marks | • Default Constructor • Setter and getter functions for all data members • A function to save information of a Student • A function to display information of a Student |
