## Calculate Distance Between 2 Points With the Euclidean Distance Formula in C

The Euclidean distance formula is used to calculate the distance between 2 points. The formula states that .

d is the distance between points, p and q, respectively. We can use the Math class for taking square and square-root of the coordinates in C#. The Math.Pow() function calculates the square of the number by passing 2 as a parameter. The Math.Sqrt() function calculates the square root of a number. So, We can apply the Euclidean distance formula with the var distance = Math.Sqrt((Math.Pow(x1 - x2, 2) + Math.Pow(y1 - y2, 2))); statement in C#. The following code example shows us how to calculate the distance between two points with the Euclidean distance formula in C#.

using System;

namespace measure_distance
{
class Program
{
static void Main(string[] args)
{
double x1, x2, y1, y2;
x1 = 12d;
x2 = 13d;
y1 = 11d;
y2 = 10d;
var distance = Math.Sqrt((Math.Pow(x1 - x2, 2) + Math.Pow(y1 - y2, 2)));
Console.WriteLine(distance);
}
}
}



Output:

1.4142135623731


In the above code, we initialized the x and y coordinates of point 1 and point 2. The variables x1 and y1 are the coordinates of point 1, and the variables x2 and y2 are the coordinates of point 2. We calculated the distance between these points with the Euclidean distance formula and displayed the result.
