Aprende Desafío: Constructores | Structs y Enumeradores

El siguiente programa tiene dos estructuras, una de ellas se llama Point, la cual define una coordenada ya que tiene un atributo/campo x y otro y. La otra estructura se llama Triangle y está compuesta por 3 objetos de tipo point. En el constructor se pasan tres objetos point para inicializar correctamente un triángulo.

Completa los espacios en blanco para finalizar los constructores de ambas estructuras.

También será un buen ejercicio de lectura de código leer todo el código e intentar comprenderlo, sin embargo, no es necesario para resolver esta tarea.

            double x1 = this.vertices[0].x;

            double y2 = this.vertices[1].y;

            // Calculating and returning the area of the triangle. 
            // This formula is easy available on the internet, you don't need to understand it.
            return (0.5) * ( x1 * (y2 - y3) + x2 * (y3 - y1) + x3 * (y1 - y2) );
        }

    static void Main(string[] args)
    {
        Point p1 = new Point(47, 17);
        Point p2 = new Point(9, 50);
        Point p3 = new Point(7, 14);

        Triangle tri = new Triangle(p1, p2, p3);

        Console.WriteLine(tri.getArea());
    }
}

Un constructor es similar a un método, sin embargo, no tiene ningún valor de retorno; además, utiliza la palabra clave public antes de su definición.

Suggested prompts:

Can you show me the code with the blanks that need to be filled?

What should the constructors for the `Point` and `Triangle` structs look like?

Can you explain how to use these structs once they are constructed?

Awesome!
