The Polygon class represents a 2 dimensional shape. It has a public field named NumSides. Create a new type of polygon called Square. It should have a public readonly field named SideLength thatβs initialized using the constructor. Use base to initialize NumSides to 4.
I am having a problem to finished it. Can someone help?
namespace Treehouse.CodeChallenges
{
class Polygon
{
public readonly int NumSides;
public readonly int Square;
public Polygon(int numSides)
{
NumSides = numSides;
}
}
}

231,269 PointsYou won't be adding anything to Polygon.
All your work will be new code added after the definition of Polygon. Your new class will be named Square and it will inherit from Polygon. It will also have a readonly field, but named SideLength, that will be initialized by the constructor much like NumSides is in Polygon.
If you haven't already, it might help to re-watch the videos at the beginning of this stage if you're unsure about how to code for inheritance.
