Exam Two Review

This exam will cover the basics of Object oriented programming, and material covered since our last test.

Objects and Classes

• Basic Class structure

  • Header file

    • Public definitions

    • Private definitions

  • Implementation file

    • Class methods

• Using classes

  • Including the class header

  • Creating objects

• Calling class methods (messages)

Designing classes

• Think first, code later

  • Separating concepts - objects from the user’s world

  • Keep responsibilities separate

  • focus on objects from the users world

  • What data are required for those objects?

  • What behavior do those objects need to provide?

  • decide on what parts of your class cna be public, and which should be private

• Types of methods:

  • Constructors * Default * Copy Constructors

  • Destructors

  • Accessor methods

  • Mutator methods

Writing classes

• Build a header file for the class

  • Know the standard template for header

• Build implementation for the class

• Add class files to project

Array topics

• Initializing arrays

• Passing arrays to functions

Searching and Sorting

• Simple searching

• Bubble Sorting

Pointers

• What is a pointer?

• How do you create a pointer?

• Pointer math (arrays).

• Pointers that point to nothing.

• Getting the address of a variable.

Linked Lists

• Management class controls access to the list

• Creating new objects with new

• What is a destructor, and why is it needed>

• What is a copy constructor and why is it needed?

Complex Numbers

• Classes create new data types

• Define the structure for your new type (in this case a real and imaginary floating point part)

• Write methods that make the type work properly

• New methods for addition, subtraction, output, etc.

  • Complex::operator+(const Complex lhs, const Complex rhs);
