Inheritance Question

Hi,

I dont understand the question. Can you help me out? Ive done my coding and cant seem to find the problem with my code

Polygon.cs
namespace Treehouse.CodeChallenges
{
    class Polygon
    {
        public readonly int NumSides;

        public Polygon(int numSides)
        {
            numSides = 4;
            NumSides = numSides;
        }
    }

    class Square : Polygon
    {
        public readonly int SideLength;
        public Square(int sideLength) : base(sideLength)
        {
            SideLength = sideLength;
        }
    }


}

You're really close there.

That last hint they gave you ... when they say "Use base to initialize NumSides to 4". They mean 4 .. literally.

So you don't want to pass it your side length .. you just pas it a 4 ( base(4) ).

Otherwise, I think you have it. :+1:
