Lab 3: Introduction to Classes and Objects

Lab Objectives:

In this lab students will learn:

The laboratory exercises basic C++ programming skills.

ü The laboratory explores the fundamental concepts of a class such as public, private members, and constructors.

Background:

 

Students have knowledge about the basic concept of class and object [data members, member function, and constructors].

 

Lab Problems:

 

Lab Problem-1:

Write a class named Employee that has the following data members:

o Name: that holds the employee's name.

o Id: is an int variable that holds the employee's id number.

o Salary: is an float variable that holds the employee’s salary.

o Department: that holds the name of the department where the employee works.

 

The class should have the following constructors and member functions:

o A Default constructor that assigns empty strings (" ") to the name, and department data members, salary to 250 and 0 to the id data members.

o A constructor that accepts the following values as arguments and assigns them to the appropriate data members: employee's name, ID, salary, and department.

o Appropriate mutator (set functions) functions that store values in these data members and accessor (get functions) functions that return the values in these data members.

o A function called AnnualSalary that compute the annual Salary.
