Answer to Question #203784 in C++ for Zzesk

Question

By implementing the concepts of classes and objects, write a C++ program that determines the distance between 2 points in a coordinate system. The coordinates of the 2 points: P1 (x1, y1) and P2 (x2, y2) are to be entered from the keyboard. The distance, d, between the 2 points is computed as: d = √(y2 - y1)^2 + (x2 - x1)^2 

Answer 1

#include<iostream>
#include<cmath>
using namespace std;
class Distance{
	private:
		int x1, y1, x2,y2;
	public:
		void setX1(int i ){
			x1 = i;
		}
			void setY1(int m ){
			y1 = m;
		}
			void setX2(int d ){
			x2 = d;
		}
			void setY2(int k ){
			y2 = k;
		}
		int getX1(){
			return x1;
		}
			int getY1(){
			return y1;
		}
			int getX2(){
			return x2;
		}
			int getY2(){
			return y2;
		}
		double calculate_distance(){
		
			int y = pow(getY2() - getY1(),2);
			int x =pow(getX2() - getX1(),2);
			int m = y + x;
			double answer =sqrt(m);
			return answer;
		}
};

	cout<<"Enter the coordinates of two points to calculate the distance between them"<<endl;
	int x1, x2, y1, y2;

	cout<<"The distance between  ("<<x1<<" , "<<y1<<") and ("<<x2<<" , "<<y2<<") is "<<d.calculate_distance()<<endl;
