subsections:

Object-oriented programming

  • high tech synonym for good

Styles of programming

  • A language supports a style of programming if it provides facilities that make it convenient (easy, safe and efficient) to use that style

  • compile/runtime checks
  • clean interpretation/ orthogonal / efficient / minimal
slide: Styles of programming

Procedural programming

  • procedures, use the optimal algorithms

Modules

  • hide the data, provide functional abstractions

Data abstraction

  • types, provide a sufficiently complete set of operations

Object-oriented -- organize your types
  • make commonality explicit by using inheritance
