Allow the capacity of a warren to vary, some warrens may be smaller and other may be larger

Within the warren class, a variable called MaxRabbitsInWarren is set to 99. The const declaration means it can't be changed during runtime. You must therefore remove the const:

private const int MaxRabbitsInWarren = 99;

Becomes:

private int MaxRabbitsInWarren = 99;

Warren Constructors

Both of the constructors below are used to create a warren. We need to add some code to both to set the size of the warren randomly.

public Warren(int Variability)
    {
      this.Variability = Variability;
      Rabbits = new Rabbit[MaxRabbitsInWarren];
      RabbitCount = (int)(CalculateRandomValue((int)(MaxRabbitsInWarren / 4), this.Variability));
      for (int r = 0; r < RabbitCount; r++)
      {
        Rabbits[r] = new Rabbit(Variability);
      }
    }

public Warren(int Variability, int rabbitCount)
    {
      this.Variability = Variability;
      this.RabbitCount = rabbitCount;
      Rabbits = new Rabbit[MaxRabbitsInWarren];
      for (int r = 0; r < RabbitCount; r++)
      {
        Rabbits[r] = new Rabbit(Variability);
      }
    }

We could therefore use the CalculateRandomValue() method to also create a random value for MaxRabbitsInWarren:

MaxRabbitsInWarren = (int)CalculateRandomValue(MaxRabbitsInWarren, Variability);

CalculateRandomValue will return a double, but we need to have an integer. Using (int) will cast the double into an integer instead.

Display Warren Size

You now need to edit the Inpsect method of the Warren class, this now needs to give a message to report the maximum number of rabbits allowed in the warren. This is the original:

    public virtual void Inspect()
    {
        Console.WriteLine("Periods Run " + PeriodsRun + " Size " + RabbitCount);
    }

With the extra code added:

    public virtual void Inspect()
    {
        Console.WriteLine("Max Warren Size: " + MaxRabbitsInWarren);
        Console.WriteLine("Periods Run " + PeriodsRun + " Size " + RabbitCount);
    }
