Input the coördinates and calculate the distance between them c#
static void Main() {
double d, x1, x2, y1, y2;
Console.Write("Enter coordinates for point A: ");
x1 = Double.Parse(Console.ReadLine());
y1 = Double.Parse(Console.ReadLine());
Console.Write("Enter coordinates for point B: ");
x2 = Double.Parse(Console.ReadLine());
y2 = Double.Parse(Console.ReadLine());
d = Math.Sqrt(Math.Pow(x1 - x2, 2) + Math.Pow(y1 - y2, 2));
Console.Write("Distance between points: " + d);
Console.ReadKey();
