Final Exam Review The final exam

• Other finals review

– CSH Review

• November 17th – 7pm – 10pm
• Gracies

– Recall

• Final: November 18th
• 12:30pm – 2:30pm
• 70-3690

Plan for today

• Everything we learned

– In less than 50 minutes!

• Course Evaluations

UML

• Use Case Diagram

– Shows scenerios of external interaction with system

• Sequence Diagrams

– Show sequence of method calls for a given use case

• Class Diagram

– Shows classes that make up your system and relationships between them

C++ Intro

• C++ is superset of C

– Designed for memory manipulation

• Source + Header file
• Compilation & Linking

C++ Tour 1

• Variables:

– Basic – Pointer – Reference – Interesting operators

• & address of
• * dereference
• -> dereference / access member

C++ Tour 2

• static
• Const
• Functions

– Pass by value

• Arrays

– Almost equivalent to pointer – New / delete / delete []

Operators

• Can redefine basic operators on classes

– Including the assignment operator – operator#

• Friends

Constructors/Destructors

• Default constructor
• Copy constructor

– If you do non-trivial work in constructor

• Should have copy constructor and operator=
• Difference between copy & operator=
• Initializer List

– Preferred way of doing things – Sometimes the ONLY way – Order of initialization

• Destructors

– If you new, you must delete

The we hade Exam 1 Inheritance I

• Basic Concepts, Terms, Syntax
• Polymorphism
• Virtual functions
• Abstract functions / classes
• Base class in Initializer list (no super)

Inheritance II

• Memory Layout of derived class

– Why you must call constructor of base class first

• Polymorphism / Slicing

Memory Management

• How/where data is stored

– Global / Heap / Stack / Code

• Runtime Stack

– Stack frame removed when function is done

• Heap

– new – delete

Memory Management

• Memory Woes

– Memory Leaks – Pointer Ownership – Dangling Reference – Overwriting Arrays – Reference to local variable

IOStreams

• Formatted vs Unformatted I/O
• Error states and format flags
• Insertion and Extraction

– Manipulators

IOStreams Templates

• Defining / using templates
• Standard Template Library (STL)

– Containers – Iterators – Algorithms – Functions

More Memory Management

• Smart Pointers

– Takes ownership of pointer – Smart pointers and STL containers – Override operator= and operator->

Software Testing

• Error / Fault / Failure
• Unit / Integration / System Test
• Preconditions / Postconditions
• White Box / Black Box Testing
• Equivalence Classes
• Assertions

Then we had exam 2 Exceptions

• Throw
• Try / catch

– Exception hierarchies – (…) – Stack unwinding

• Exception specification

– Not required but guarantee if there

Exceptions

• Error conditions

– Unexpected exception – Uncaught exception

• Exceptions and Memory Management
• Exceptions vs Assertions

Function Pointers

• Syntax
• Declaration and Assignment

– Signature must be the same!

• Functors

– Overrides the operator() – Can have state and extra methods

More Inheritance

• VTABLES

– That silly =0 syntax – Virtual functions and construction – Virtual functions and destructors

Ethics

• Hackers
• Free Software
• Open Source
• GNU Public License
• Linux woes

– SCO vs. IBM

And there you have it!

• Any questions?
• Thanks to all…
