41. The Joys (and Woes) of Programming

42. Programming Why is there no programming in this course? How many of you have taken a programming course?

43. Computer Programming Think of a computer as a robot. What do you want it to do?

44. Important to Remember A computer isn’t smart enough to make a mistake--without our help. Computers only do what they are instructed to do by instructions via a program.

45. Object-Oriented Languages: Use Combinations of Objects Fourth-Generation Languages: Use Natural and Nonprocedural Statements High-Level Languages: Use Brief Statements or Arithmetic Notation Assembler Languages: Use Symbolic Coded Instructions Machine Languages: Use Binary Coded Instructions Categories of Programming Languages

46. Program Compilation C Cobol Fortran Compiler Program Object Code Source Code Computer Compilation Computer Processing Results Data

47. Computer Programming There are over two thousand known computer programming languages. Which flavor do you like?

48. Computer Programming Languages Python REXX SGML Sisal TCL/TK TeX VHDL WEB (cweb, fweb) Z Erlang Forth FORTRAN Haskell Java Lisp Occam Oz Pasqual Perl Postscript Prolog ABC Ada Basic, Visual BETA C C++ Elisp Cecil COBOL Dylan (OODL) Eclipse Eiffel (OO) Elf

49. Worth Remembering Programming is both a science and an art. The science part is that there are rules (syntax) that must be adhered to for a specific language. The art is that there are clever, innovative, even creative ways to do a program to accomplish a specific task.

50. The Joys of Programming 1. The satisfaction from making something that works. 2. The pleasure of making things that are useful to others. 3. The fascination of fashioning complex, puzzle-like objects of interlocking moving parts and watching them work to accomplish things. 4. The fun of always learning from the non-repetitive nature of the task. 5. Working in a medium that is only slightly removed from pure thought levels.
