Question

How to calculate the Euclidean distance between two points in C#

Answer 1

// The Euclidean distance is a measure of the straight-line distance 
// between two points in a 2D or 3D space

using System;

class EuclideanDistance
{
    // Function to calculate Euclidean distance
    static double CalculateEuclideanDistance(double x1, double y1, double x2, double y2) {
        return Math.Sqrt(Math.Pow(x2 - x1, 2) + Math.Pow(y2 - y1, 2));
    }

    static void Main()
    {
        double x1 = 3.0, y1 = 4.0;
        double x2 = 5.0, y2 = 9.0;

        double distance = CalculateEuclideanDistance(x1, y1, x2, y2);

        Console.WriteLine($"Euclidean Distance: {distance:F5}");
    }
}
