Study Notes

Course Overview

Course title: CS -- 212: Object Oriented Programming
Offered by the College of Electrical and Mechanical Engineering, NUST
Instructors: Dr. Soyiba (Course Instructor), Engr. Ayesha Khanam (Lab Instructor)

Lab Task Introduction

Focus on creating a class in programming as part of Lab #02
Core objective: Understand and implement class structures and member functions

Class Structure: Employee

Class named Employee created to hold employee-related data
Key attributes defined as private:
- EmployeeID: double type, uniquely identifies employees
- EmployeeName: string type, stores the name of the employee
- EmployeeSalary: double type, represents the employee's salary

Member Functions

Setters: Functions responsible for inputting data into the class
- setEmployeeID(double id): Sets the employee ID
- setEmployeeName(string n): Sets the employee's name
- setEmployeeSalary(double s): Sets the employee's salary
Getters: Functions that retrieve data from the class
- getEmployeeID(): Returns the employee ID
- getEmployeeName(): Returns the employee's name
- getEmployeeSalary(): Returns the employee's salary
Display Function:
- displayEmpDetails(): A function intended to output the employee details (incomplete code requires implementation)

Programming Elements

The use of access modifiers (private, public) ensures encapsulation, protecting data integrity
Utilizes standard library features (iostream and string) to handle input/output and string manipulations

Description

This quiz focuses on the fundamentals of object-oriented programming specifically in creating classes in C++. Students will learn to create an Employee class with functions to input and display employee details. This hands-on lab is essential for mastering the basic concepts of OOP.
