2. What’s Next >>>>>

4.  Ada Lovelace mathematician in mid-1800’s.
 Languages provided no abstraction from the computer
hardware.
 1940’s - general-purpose computers
 Machine Language
 First Generation
 Assembly Language
 Second Generation

5.  Ancestors of Today’s Languages.
 Abstracted away the underlying complexities of
hardware environment.
 1950’s - Fortran, COBOL
 Third Generation Languages

6.  1960’s – 1970’s
 Increase the level of Abstraction
 Make programs easier to develop and maintain.
 Language Enhancements
 Programming Paradigms
 The GOTO Controversy.
Paradigms>>>>
GOTO >>>>

7.  1990’s – increased developer productivity.
 Memory Leaks, portability
 JVM & CLR
 Frameworks

9.  Formula Translation (FORTRAN) in 1954 led to...
 Over 2000 languages.
 How many languages in use today?
 Difficult to say
 Legacy Software(using outdated languages) is
everywhere.
 Why can’t we just use one language?

10.  Everyone knows it in one form or another.
 Loops & Conditions.
 Design Patterns.
 APIs
 How many of your friends know something called Rule
Engine?

11.  Can get real Complex.
 Tower of Babel.
The End

12.  It is just a small piece of software in the big picture.
 MAYBE (fuzzy logic)
 An = 4an-1-3 (recursive rules)
 No Standards
 New Learning.
 Difficult to Test.

13. <<<<Back

14.  Considered Harmful
 Led to the concept of Structured Programing
 Idea: Code is clearer if we restrict to a few control
structures.
 Loops have single entry, single exit
<<<<<<Back

15.  Procedural programing  Logic Programing
 Program can be broken into  Based on use of declarative
procedures (or subroutines or statements in the language of
functions) mathematical logic.
 Examples:  Examples:Prolog
Fortran, Algol, Cobol, C, Pas
cal
 Object-oriented programing
 Program is seen as a group of
cooperating objects
 Ideas:
encapsulation, inheritance
 Examples:C++, C#, Java, Pyt
