4,405 PointsDid you define your Square class as an inner class of the Polygon class? I cant reason this one out :(
My square class is derived from the polygon class and is defined right after the polygons scope. i have move the square class inside the polygons scope, before the scope, and after the scope. all have not worked. what am i missing here?
namespace Treehouse.CodeChallenges
{
class Polygon
{
public readonly int NumSides;
public Polygon(int numSides)
{
NumSides = numSides;
numSides = 4;
}
}
class Square : Polygon
{
public readonly int SideLength
public Square(int sideLength) : base (NumSides)
{
}
}
}

So you shouldn't change anything in the Polygon class (so you shouldn't be setting NumSides to 4 on line 10). What we're trying to do is define the Square class so that all squares will have 4 sides. On line 16 where you're calling base, this is where we want to be passing in the number 4, saying all squares will always have 4 sides. (And FYI we don't have access to the NumSides parameter in this scope here).
namespace Treehouse.CodeChallenges
{
class Polygon
{
public readonly int NumSides;
public Polygon(int numSides)
{
NumSides = numSides;
}
}
class Square : Polygon
{
public readonly int SideLength;
public Square(int sideLength) : base(4)
{
SideLength = sideLength;
}
}
}
