      Next project due at start of final. Next quiz is the comprehensive final.

    Glossary

  1. accessor::=`A Function that accesses information in an object with out changing the object in any visible way". In C++ this is called a "const function". In the UML it is called a query.
  2. Algorithm::=A precise description of a series of steps to attain a goal, [ Algorithm ] (Wikipedia).
  3. class::="A description of a set of similar objects that have similar data plus the functions needed to manipulate the data".
  4. constructor::="A Function in a class that creates new objects in the class".
  5. Data_Structure::=A small data base.
  6. destructor::=`A Function that is called when an object is destroyed".
  7. Function::programming=A selfcontained and named piece of program that knows how to do something.
  8. Gnu::="Gnu's Not Unix", a long running open source project that supplies a very popular and free C++ compiler.
  9. mutator::="A Function that changes an object".
  10. object::="A little bit of knowledge -- some data and some know how". An object is instance of a class.
  11. objects::=plural of object.
  12. OOP::="Object-Oriented Programming", Current paradigm for programming.
  13. Semantics::=Rules determining the meaning of correct statements in a language.
  14. SP::="Structured Programming", a previous paradigm for programming.
  15. STL::="The standard C++ library of classes and functions" -- also called the "Standard Template Library" because many of the classes and functions will work with any kind of data.
  16. Syntax::=The rules determining the correctness and structure of statements in a language, grammar.
  17. Q::software="A program I wrote to make software easier to develop",
  18. TBA::="To Be Announced", something I should do.
  19. TBD::="To Be Done", something you have to do.
  20. UML::="Unified Modeling Language".
  21. void::C++Keyword="Indicates a function that has no return".
