 Lab 04: GET and SET Functions

Introduction
This lab is about getter and setter functions in OOP.

Objective
To understand the difference between get and set functions and their usability in the object
oriented paradigm

Tools/Software Requirement

 Microsoft Visual Studio

Instructions
You are encouraged to use good programming conventions by entering appropriate comments,
using indentations, and using descriptive variable names in your programs. Insert the
solution/answer in this document as directed below. You must also submit this Word document
on the LMS within the time of the lab.

Task 1

Create a class Rectangle. The class has attributes length and width, each of which defaults to 1.
Provide methods that calculate the perimeter and the area of the rectangle. Provide set and get
methods for both length and width. The set methods should verify that length and width are each
floating-point numbers greater than or equal to 0.0 and less than 20.0. Write a program to test
class Rectangle.

Code :
#include <iostream>

using namespace std;

class Rectangle{

private:

float length,width,area,perimeter;

CS212: Object Oriented Programming Page 2

 public:

Rectangle(){

length=1;

width=1;

};

void setdimensions(){

cout<<"Please enter the length of rectangle : ";

cin>>length;

while(length<0||length>=20){

cout<<"Please enter the length between 0.0 and 20"<<endl;

cout<<"Please enter the length again ";

cin>>length;

cout<<"Please enter the width of rectangle : ";

cin>>width;

while(width<0||width>=20){

cout<<"Please enter the width between 0.0 and 20"<<endl;

cout<<"Please enter the width again : ";

cin>>width ;

perimeter=2*(length+width);

CS212: Object Oriented Programming Page 3

 area=length*width;

void getdimensions(){

cout<<"Perimeter of the rectangle is "<<perimeter<<" units"<<endl;

cout<<"Area of rectangle is "<<area<<" units"<<endl;

};

int main(){

Rectangle R1;

R1.setdimensions();

R1.getdimensions();

return 0;

Task 2

Create a class called Employee that includes three pieces of information as instance variables—a
first name, a last name, and a monthly salary. Provide a set and a get method for each instance
variable. If the monthly salary is not positive, set it to 0.0.Write a test application named
EmployeeTest that demonstrates class Employee’s capabilities. Create two Employee objects
and display the yearly salary for each Employee. Then give each Employee a 10% raise and
display each Employee’s yearly salary again.

Code:
#include <iostream>

#include <string>

using namespace std;

class Employee{

private:

string fname,lname,fname1,lname1;

int
salary,monthly_salary,incremented_salary,yearly_salary,salary1,monthly_salary1,incremented_s
alary1,yearly_salary1;

public:

void setfunction1(){

cout<<"Please enter the first name of the 1st employee : ";

getline(cin,fname);

if ( fname.length() > 25 )

fname = fname.substr( 0, 25 );

CS212: Object Oriented Programming Page 5

 cout << "Name \"" << fname <<"\" exceeds maximum length (25).\n"<< "Limiting first Name
to first 25 characters.\n" << endl;

};

cout<<"\nPlease enter the last name of the 1st employee : ";

getline(cin,lname);

if ( lname.length() > 25 )

lname = lname.substr( 0, 25 );

cout << "Name \"" << lname <<"\" exceeds maximum length (25).\n"<< "Limiting lastName
to first 25 characters.\n" << endl;

};

cout<<"\nPlease enter the salary of the 1st employee : ";

cin>>salary;

if (salary>0){

monthly_salary=salary;

else{

cout<<"\nInvalid salary entered. Salary set to 0.0";

monthly_salary=0;

};

yearly_salary=monthly_salary*12;

incremented_salary=yearly_salary+(0.1*yearly_salary);

};

fname1 = fname1.substr( 0, 25 );

Name to first 25 characters.\n" << endl;

asks the user for employees data and then displays that data.\n\nUser enters first and last name of
the employees and class checks for whether the names are greater than 25 chars and if so, it
limits the name to first 25 chars to help memory management.\n\nUser is then asked to enter the
