Programming Exercise

Problem # 15:

Write a program that inputs x, y coordinates for two points and computes the
distance between two points using the formula: Distance = sqrt( (x2-x1)^2 + (y2-y1)^2 )

Solution:

#include<iostream>
#include<conio.h>
#include<math.h>
using namespace std;
int main()
{
    int x1, x2, y1, y2;    //x-coordinate, y-coordinate
    float d;        //distance
    cout<<"Enter x, y coordinate for point 1 : ";
    cin>>x1>>y1;
    cout<<"Enter x, y coordinate for point 2 : ";
    cin>>x2>>y2;
    d = sqrt( pow(x2-x1,2) + pow(y2-y1,2) );
    cout<<"Distance is: "<<d;
    getch();
    return 0;
}
