write a program to read coordinates of two points and calculates the distance between them as per following formula: d=sqrt(x1-x2)*(x1-x2)+(y1-y2)*(y1-y2)

PROGRAM

write a program to read coordinates of two points and calculates the distance between them as per following formula:
 d=sqrt(x1-x2)*(x1-x2)+(y1-y2)*(y1-y2)

#include<iostream.h>
#include<stdlib.h>
#include<math.h>
    int main()



   {
           system("cls");
           double  distance,x1,x2,y1,y2;
             cout<<"Enter coordinates(xy) of point1:";
             cin>>x1>>y1;
             cout<<"Enter coordinates(xy) of point2:";
             cin>>x2>>y2;
          distance=sqrt((x1-x2)*(x1-x2)+(y1-y2)*(y1-y2));
cout<<"The distance between("<<x1<<","<<y1<<")and("<<x2<<","<<y2<<")is:"<<distance<<endl;;
          return 0;

    }
========================================================================
OUTPUT:
Enter coordinates(xy) of point1:5 6.5
Enter coordinates(xy) of point2:2 4.1

The distance between(5,6.5)and(2,4.1)is:3.841875
