Question

Write a program to print the area of a rectangle by creating a class named'area' having two function . First function named as 'read data' take the length and breadth of the rectangle as parameters and the second function named as 'calculate area' return the area of the rectangle

Answer 1

#include <iostream>
using namespace std;


class area{
private:
	float length;
	float breadth;
public:
	void readData(float length,float breadth){
		this->length=length;
		this->breadth=breadth;
	}


	float calculateArea(){
		return this->length*this->breadth;
	}
};
int main()
{
	float length;
	float breadth;
	area _area;
	cout<<"Enter length of a rectangle: ";
	cin>>length;
	cout<<"Enter breadth of a rectangle: ";
	cin>>breadth;
	_area.readData(length,breadth);
	cout<<"The area of the rectangle: "<<_area.calculateArea()<<"\n";


	cin>>length;
	return 0;
}
