History of C++  WWII Artillery trajectory Machine language Assembly language  ADD, MOV  High-level language: BASIC, COBAL Compiler Linker Advantages  Easy to develop  distributable  Well-written and easy-to-maintain > computer cost

Terminology  Program Source code Executable file  Structural (procedural) language Split and conquer Data-driven Lack of reusability  Object-oriented language Treat data and the procedures that act upon the data as a single “object” Four pillars  Encapsulation Encapsulation  Data hiding  Inheritance  polymorphism polymorphism

How C++ enovled CCCC  C++ Bjarne Stroustrup  ANSI  No need to learn C first!
