In this article I would like to share with you a sample program that will compute the area and base of the rectangle using Classes in C++. The code will give you a first hand experience how to create an object, methods and attributes in object oriented programming in C++.
If you have some questions about programming, about my work please send me an email at jakerpomperada@gmail.com and jakerpomperada@yahoo.com. People here in the Philippines can contact me at my mobile number 09173084360.
Thank you very much and Happy Programming.
Sample Program Output
Program Listing
#include <iostream>
using namespace std;
class rectangle {
private:
float base,height;
public:
float area(float b,float h)
{
return(b*h);
}
float process_data();
float display_data();
};
float rectangle :: process_data()
{
cout << "\n";
cout<<"\t\t AREA OF A RECTANGLE\n";
cout << "\n";
cout<<"\nEnter Base : ";
cin>>base;
cout<<"\nEnter Height : ";
cin>>height;
cout << "\n\n";
cout<<"\nArea = "
<<area(base,height)
<<" Square Units\n";
cout << "\n\n";
system("pause");
}
float rectangle :: display_data()
{
float math;
math = process_data();
}
main() {
rectangle number;
number.display_data();
}
