  1. Object Oriented Design and Programming Alan Goude Email: a.goude@shu.ac.uk Room: Sheaf 9323

  2. Unit delivery and assessment • weeks 1 - 6 • 2hr lectures, 1hr labs • weeks 7 -12 • 1hr lectures, 2hr labs • 100% coursework assessment • Two Assignments each contributing 50%

  3. Topics - • The object oriented approach OOA,OOD and OOP • C++ Stream Input/Output • Reference variables • Classes • Terminology • Class members – data and functions(methods) • Class access – public, private & protected • Separation of interface from implementation • Constructor and destructors • function overloading • Dynamic memory allocation • Object aggregation and composition • UML notation for classes and class aggregation.

  4. Topics - • Operator overloading • Additional class features • Friend functions • Static members • Inheritance • Polymorphism • Abstract classes, Virtual functions • Templates, Standard Template Libray & More UML (time permitting)

  5. Books • Thinking in C++ by Bruce Eckel • Vol.1 (basics) and Vol.2 (advance features) • Assumes knowledge of ‘C’ • Free Electronic versions available from- • http://www.mindview.net/Books • C++ : How to program by Deitel & Deitel • See info at http://www.deitel.com/ • Fourth Edition available Oct 2002 • Includes a version of Microsoft Visual C++

  6. Other books and information sources • Object-Oriented Analysis and Design with Applications by Grady Booch • Unified Modelling Language User Guide by Grady Booch, Ivar Jacobson, James Rumbaugh • UML Distilled: A Brief Guide to the Standard Object Modeling Language (2nd Edition) by Martin Fowler, Kendall Scott • My Web page - http://www.shu.ac.uk/schools/eng/teaching/ag1 • Try a www.google.com search

  7. Object Oriented Design and Programming • OOD – Major proponents and developers • Grady Booch, Ivar Jacobson, and James Rumbaugh • Unified Modelling Language (UML) • OOP – Several OOP languages • Smalltalk, Eiffel. Pure OOPL • C++, Java. Said to be object based OOPL

  8. Software Tools • Object Oriented Programming (OOP) • C++ • Using Microsoft Visual Studio C++ compiler • Object Oriented Design (OOD) • UML (Unified Modelling Language)

  9. Object Model • Key ideas • Abstraction • Encapsulation • Modularity • Hierarchy • Minor elements of the object model • Typing (language dependent – data typing) • Concurrency (OS dependent) • Persistence

  10. Abstraction • Helps to deal with complexity by focusing on certain features and suppressing others. • Focus on interface (outside view) • Separate behaviour from implementation

  11. Hierarchy • A way of ordering abstractions • Object hierarchical abstractions (“HAS A” or “PART OF” relationship) • Interfaces and behaviours at each level • Higher levels are more abstract

  12. Encapsulation • Also known as information hiding • Hides the details of the implementation • Complementary to abstraction

  13. Abstraction, Encapsulation and Software Design • Interface should be simple, providing the required behaviour. • User is presented with high level abstract view. The detail of the implementation is hidden from the user. • The designer may change the implementation keeping the interface the same.

  14. Modularity • A common “Divide and conquer” approach • Partitions a problem into sub-problems reducing complexity • Modularity packages abstractions into discrete units • In C++ classes are the basic modules providing encapsulation and abstraction

  15. Re-usability - Inheritance • Class Hierarchies • Derived class inherits properties and behaviour of a base class • Allows code re-use. • Derived classes can have • additional properties and behaviour, • or over-ride inherited behaviour.
