Working with structs in swift?

Example:

  struct Point {
      var x: Int
      var y: Int
  }
  var p = Point(x: 5, y: 10)
  

Structs are used to define custom data types. The example shows a basic structure for a 2D point.

Solution:

  struct Point {
      var x: Int
      var y: Int
      func distance(to point: Point) -> Double {
          let dx = Double(x - point.x)
          let dy = Double(y - point.y)
          return sqrt(dx*dx + dy*dy)
      }
  }
  var p1 = Point(x: 5, y: 10)
  var p2 = Point(x: 15, y: 20)
  print(p1.distance(to: p2))
  

The solution adds a method to the struct to calculate the distance between two points.
