Class Constructors

• When the ItemInfo class is defined as above, a special method called a constructor is defined behind the scenes.
• A constructor's name is always the same as the class name.
• A constructor can be used with the new operator to dynamically create a new instance (object) of a class:

  	ItemInfo* item = new ItemInfo;  // note the absence of arguments

• As with structs and arrays, the new operator returns a pointer to the object.
• A constructor with no arguments, called the default constructor, does not initialize the object's instance variables.
