This is a subclass of Card.

The Code

class ToolCard : Card
    {
        protected string ToolType;
        protected string Kit;

        public ToolCard(string t, string k) : base()
        {
            ToolType = t;
            Kit = k;
            SetScore();
        }

        public ToolCard(string t, string k, int cardNo)
        {
            ToolType = t;
            Kit = k;
            CardNumber = cardNo;
            SetScore();
        }

        private void SetScore()
        {
            switch (ToolType)
            {
                case "K":
                    {
                        Score = 3;
                        break;
                    }
                case "F":
                    {
                        Score = 2;
                        break;
                    }
                case "P":
                    {
                        Score = 1;
                        break;
                    }
            }
        }

        public override string GetDescription()
        {
            return ToolType + " " + Kit;
        }
    }

New Variables

The ToolCard has additional variables not found in the parent class. These are 'ToolType' and 'Kit', they are both protected which means they would be available in any subclass of ToolCard.

The Constructors

ToolCard has 2 constructor methods, this is okay as long as they have different parameters. These are the constructors:

        public ToolCard(string t, string k) : base()
        {
            ToolType = t;
            Kit = k;
            SetScore();
        }

        public ToolCard(string t, string k, int cardNo)
        {
            ToolType = t;
            Kit = k;
            CardNumber = cardNo;
            SetScore();
        }

So here 1 constructor accepts parameters of 'string t, string k' and the other accepts parameters of 'string t, string k, int cardNo'.

'base()' will also run the base constructor method.

SetScore

The SetScore method is labelled 'private', therefore this would not be available in any subclass of ToolCard.

GetDescription

The GetDescription method will override the method from the Card class. This method would be marked 'virtual' in the Card class.
