Subclass Constructors

• As usual, we define the convenience type OxfordShirt:

    typedef class OxfordShirtInfo* OxfordShirt;    

• When an OxfordShirtInfo object is created, the constructor needs four pieces of information:

    OxfordShirt shirt = new OxfordShirtInfo(49.99, "Navy blue", 15, 33);    

• So the constructor definition will begin:

      OxfordShirtInfo(double p, string c, int n, int s) ...     

  n and s, the neck size and sleeve length, can be stored in the object.
• Q: How to handle the price and color?
  A: Have the superclass, ItemInfo, store them using its constructor.
