  • Will be honest and direct with you and expect the
    same in return from you.
  • Will try to be consistent and fair to all
    students.

5
Course Objectives
  • Introductory course in computer programming.
  • Assumes no computer science background.
  • Solving problems of a general nature using C.
  • Understand algorithms and be able to write
    programs of moderate complexity

6
Textbooks
  • Essential C for Engineers and Scientists, Jeri
    R. Hanly
  • Introduction to Matlab, Delores M. Etter and
    David C. Kunicky

7
Computer Use
  • Use the Visual C compiler on the IBM PCs in CAC
    Labs
  • Access UserID and password
  • At least 2 3.5 diskettes

8
Grades
  • Two midterm examinations - 200 points each
  • Exam 1 Tuesday 9/26 at 630 P.M.
  • Exam 2 Monday 11/6 at 815 P.M.
  • Final examination 250 points
  • Time and date will be announced by University
  • Homework Assignments 250 points
  • Recitation 100 points
  • Total 1000
    points

9
Large Class
  • Lectures
  • Attend!
  • Ask questions
  • More responsibility on student
  • Be courteous to neighbor
  • Recitations
  • Attend
  • More one to one

10
General Information
  • Lectures will not follow texts exactly
  • Expected to attend class
  • Responsible for material covered in class,
    announcements, assignments
  • Exam grades will not be individually curved!

11
General Information (Cont.)
  • Copies of handouts will be on shelves outside my
    office
  • Assignments should be done using C compiler on
    PCs in CAC labs
  • Some exam questions may be based on these
    computers

12
General Information (Cont.)
  • Assignments and files placed on Network I drive
  • Class web page

13
Questions?
14
What is a computer
  • Electronic device
  • Tool
  • Not a magic black box

15
Advantages
  • Fast
  • Reliable
  • Does not get tired
  • Does what you tell it

16
Disadvantages
  • Does what you tell it
  • Is only as good as the programs and data that are
    entered gt GIGO
  • Has no intuitive skill

17
What can a computer do?
  • Simple arithmetic
  • Comparisons/decision making
  • Communication

19
Primary Storage Unit
  • Read Only Memory
  • Random Access Memory
  • Basic Input/Output System

20
Memory Organization
  • Two circuit states correspond to 0 and 1.
  • Bit (short for binary digit) refers to a single 0
    or 1. Bit patterns represent both the computer
    instructions and computer data.
  • 1 byte 8 bits
  • 1 KB 1024 bytes
  • 1 MB 1024 x 1024 1,048,576 bytes
  • Word amount of memory that computer views
  • as a single unit

Memory
22
Memory
Operating system
Your Program
data
23
Input Devices
  • Keyboard
  • Mouse
  • Disk(s)
  • Tape drives
  • Touch screen
  • etc.

24
Output Devices
  • Monitor/Cathode Ray Tube
  • Disks
  • CDs
  • Printers
  • etc.

25
Secondary (Auxiliary) Storage
  • Disk Drives
  • Hard/fixed/internal
  • Floppy
  • CD
  • Removable Media

26
Remember
  • Memory (primary storage) is different from disk
    space (secondary storage)!

27
Hardware vs Software
  • Hardware
  • Physical Components
  • Anything you can touch!
  • Software
  • Anything that is not hardware
  • programs

28
Various types of software
  • Operating Systems
  • Application Software
  • Games
  • Utilities

29
Algorithm vs Program
  • Algorithm Step-by-step process for solving a
    problem in a finite time.
  • Program Algorithm translated into a language

30
Remember!
  • All programs are algorithms, but not all
    algorithms are programs!
