CS 202 Fall 2013
In-Class Challenge for Thursday, September 19, 2013

This challenge deals with a C++ class StarRect. It is initially specified as follows. What you are actually to do is found below.

Class StarRect Initial Specification

• Class StarRect should be implemented in header file starrect.h and source file starrect.cpp.
• An object of type StarRect should act as if it maintains two pieces of data:
  • An int holding the width of a rectangle.
  • An int holding the height of a rectangle.
• Class StarRect should have the following member functions:
  • A default constructor. This can set the data members however you want.
  • A two-parameter constructor that takes two int parameters. It sets its width equal to the first parameter and its height equal to the second.
  • Get and set functions for the two numbers, written as usual, and named getWidth, setWidth, getHeight, setHeight.
  • Function print. This should take an optional ostream parameter; use cout if the parameter is not given. It should print to the given stream a rectangle of stars (“*”) with the given width and height, ending with a newline. For example, if the width is 4 and the height is 3, then the following should be printed to the stream.

• The class should be implemented according to standard conventions regarding header & source file separation, etc.
• The const qualifier should be used correctly.
• Your package should compile with the test program test_starrect.cpp.

What to Do

Do as many of the following as you can before class ends. After each, please show me your work.

1. Write minimal versions of files starrect.h and starrect.cpp that compile with the test program test_starrect.cpp.
2. Implement class StarRect as above, so that all tests pass.
3. Add an additional option to the class: allow a character other than “*” to be used in the rectangle. The resulting class should still compile with the test program and pass all tests.
