Course Information

• Good news No assignment
• Attending all labs is a must.
• Finish all exercises from each lab. show them
  in front of me else, you wont get any mark for
  that particular lab.
• One midterm examination
• One final examination

4
Division of Laboratory

• 50 lecture revision (1 hour)
• 50 working on lab. exercises (1 hour)
• Later in this semester, we will spend more times
  on lab. exercises
• RecommendationTry to do the exercises at home,
  and bring questions to the class

Course Objectives

• An introduction to computers fundamental
  programming techniques
• Learn the different thinking logics between
  humans computers
• Use C as the programming tool
• How to write codes
• How to make them executable (i.e. compile)
• How to debug codes

6
What is hardware?

• Could it be classified as a physical material?
• Are all hardware visible?
• Do all hardware require power to run?
• Definition from WikipediaComputer hardware is
  the physical part of a computer, including the
  digital circuitry.http//en.wikipedia.org/wiki/C

7
What is software?

• Can we physically damage software?i.e. Is it
  possible to break Windows XP?
• Are all software visible?
• Can we touch any software?
• Definition from WikipediaComputer software (or
  simply software) is the programs that enable a
  computer to perform a specific taskhttp//en.wik

Programming Cycle
Start
Debug
Write (Program)
You will survive if you write a good code
Execute (Run)
Compile
11
Microsoft Visual C

• Microsoft version of C
• Its standard does not confined to ISO C
• Provide a user-friendly environment
• Rapid Application Development (RAD)
• Easy to write/compile/debug codes
• Compilation and execution are integrated into a
  single button

Golden Rules to Learn Programming

• Forget everything you learnt from maths. classes
• Breaking down a huge problem into some small
  problems
• Dont try to think/write a large program in one
  goal
• Always do testing in the middle of coding
• Try to learn the way (how stupid) computers work
