Project 6 Due

Study 5.7-5.8 page 249-253

5.7 Accessing data fields

Would your watch work better if it had a hole in it and you could poke a knife into it?

5.8 Comparing Member Functions with Normal Functions

Normal functions are outside of classes and are called without any object:

  function(argument)

1. cout << function(argumentValue);

   Member functions belong to classes. They are declared inside the class

    	class Class{ ........ type function(parameters); .... };

   and defined as being in the Class:

   	Class::function(arguments)

   Outside the class they are always called with objects.

     object.function(arguments)

   In methods in the class the object is implicit (*this).

   C++ gets confused if you muddle them up.

Advanced Topic 5.1 -- initializing fields

Out of sequence -- go back see this neat abbreviation later.

Syntax 5.4 Constructor with field initialization

 		ClassName::ClassName(parameters): fields

(Only works with constructors, not mutators or accessors:-(

Review Questions

Do as many of R5.14, R5.15, R5.16, R5.17, R5.18, R5.19 as you can and hand in one for credit.

Exercise -- Design and code a class that models a Card

[ cardshark0.cpp ] (before class) and [ cardshark.cpp ] (after class).
