Determine the distance between point x1 y1 and point x2 y2 a
     Determine the distance between point (x1, y1) and point (x2, y2), and assign the result to points Distance. The calculation is:  Distance = SquareRootOf (x2 - x1)^2 + (y2 - y1)^2  You may declare additional variables.  Ex: For points (1.0, 2.0) and (1.0, 5, 0), points Distance is 30.  
  
  Solution
#include <iostream>
 #include <cmath>
 #include <iomanip>
using namespace std;
int main()
 {
 double x1,x2,y1,y2;
 double pointDistance = 0.0;
 double diff1,diff2;
 
 
    cout << \"Enter X1 Value\" << endl;
    cin >> x1;
   
   
    cout << \"Enter X2 Value\" << endl;
    cin >> x2;
   
   
    cout << \"Enter Y1 Value\" << endl;
    cin >> y1;
   
   
    cout << \"Enter Y2 Value\" << endl;
    cin >> y2;
   
    diff1 = x2 - x1;
    diff2 = y2 - y1;
   
    pointDistance = sqrt(pow(diff1,2) + pow(diff2,2));
   
    cout << \"Points Distance :\"<< setprecision(1) << fixed << pointDistance <<endl;
   
   
   
    return 0;
 }
