Object-oriented programming in C++

• A simple example: the cookie jar.
• Variations on the cookie jar theme.
• Defining and using classes in C++. The cookie jar example.

• Classes: introduction to object-oriented programming.
  • A class is like a struct but with extra stuff added to it: functions that work only on objects of that type.
  • Object-oriented programming: induces a certain way of thinking, whereas programs manipulate objects using only the methods (or functions) that are allowed to be applied on those objects.
  • Defining classes in C++. An example. Cookie Jar abstract data type.
  • Header files.
  • Compiling complex programs with many source files using Makefiles.
• Lab: copy, test and understand the Cookie Jar example. Then modify the main program by adding a menu-based user interface, which allows the user to select the class function to be tested next.

  Stacks

  • The Stack abstract data type an applet.
  • For homework: use the Stack abstract data type to guide your design. Implementation in C++. Start in class. To be fully implemented in Homework 5.

  Summary of C++ and Unix basics for working with classes

  • Structure of a C++ program using classes (header file, implementation file, makefile, testdriver).
  • Wisely using header files. Example: the bool.h header file in the stack class example.
  • Makefiles: what they are and how to use them.
    • Compiling a class implementation without creating an executable file.
    • Creating an executable file from previously compiled object files.
    • Compiling only the files that have been modified, or which depend on other files that have been modified.
    • Makefiles. An example of a good Makefile for the hwk stack exercise.
  • Tutorial on the make utility.
  • Problems when compiling on both grendel and hermite. Read this carefully!!!
