Prompt the user for two points (x1, y1), (y1, y2). Write a function that calculates the distance between the points. For a refresher on how to calculate the distance between two points, click here: http://www.mathwarehouse.com/algebra/distance_formula/index.php

Start with this code:

#include <iostream>

// YOUR CODE GOES BELOW HERE

// TO HERE

// DO NOT CHANGE ANYTHING BELOW HERE

int main() {

double x1, y1, x2, y2;

cout << "Enter x1: ";

cin >> x1;

cout << x1 << endl;

cout << "Enter y1: ";

cin >> y1;

cout << y1 << endl;

cout << "Enter x2: ";

cin >> x2;

cout << x2 << endl;

cout << "Enter y2: ";

cin >> y2;

cout << y2 << endl;

cout << "The distance is ";

cout << distance(x1, y1, x2, y2) << endl;

return 0;

}

 

 

 

 

 

Sample run #1:

Enter x1: -5

Enter y1: 8

Enter x2: 0

Enter y2: -4

The distance is 13

 

 

 

Sample run #2:

Enter x1: 12.5

Enter y1: 18.7

Enter x2: -13.9

Enter y2: -29.5

The distance is 54.9563
