  1. Introduction CMSC 104 Problem Solving and Computer Programming Section 401, Thurs. 7:00-9:30 pm, ACIV-305 Fred Kuss fkuss1@umbc.edu Office: ITE 212 Mail Box is in: ITE 325

  2. Text Books • Required Text: “C How to Program” by Deitel / Deitel Fourth Edition, ISBN# = 0-13-142644-3

  3. Optional Text Books • Computer Confluence by: George Beekman ISBN # = 0130882372 • Computers in your Future by: Bryan Pfaffenberger ISBN # = 0130898155

  4. Optional Text Books • Foundations of Computer Science by: Behrouz A. Forouzan ISBN # = 0534-37968-0 • The Computer Continuum by: Kurt Lauckner ISBN # = 0130898139

  5. Am I in the right class? • CMSC 104 • Assumes NO programming experience • Does NOT count towards your CS major • Prepares you for CMSC 201 • CMSC 201 • Assumes some programming experience • First CMSC course for CS majors • Also required for IFSM majors • More challenging

  6. What Will We Cover? • General computer hardware and • software concepts • Basic computer use • Problem solving • Basic computer programming in • the C programming language

  7. General Hardware and Software Concepts • Introduction to computer architecture • Data representation and memory • usage • Introduction to operating systems • UNIX/Linux, Windows 95,98,NT,2000

  8. Basic Computer Use • Basic use of • an operating system (Linux) • e-mail (pine) • a text editor (pico/xemacs) • the Internet (Netscape and/or • Internet Explorer)

  9. Problem Solving • Problem solving and algorithm • development • general vs. specific solution to a • problem • use of top-down design • use of pseudocode • algorithm (code) reuse

  10. Basic Computer Programming in the C Programming Language • Compiling, linking, and executing a • computer program • Testing a computer program • C programming language basics

  11. Syllabus • On the Web • “Lecture Schedule” and Grades are also posted on the Web • Refer to the Web throughout the semester

  12. Getting a GL Account at UMBC • You MUST have a GL account • Go to room ECS 020 (in the basement) and ask at the desk, OR • Using the Internet, go to: accounts.umbc.edu (NO www.) • Your account can be used in approximately 1/2 hour

  13. Changing your Linux password • Login by entering your id and password given on the sheet • At the Linux prompt type: passwd <Return> • You will be prompted for your new password; type it in and press <Return> • You will be asked to type the new password again

  14. Changing your Linux password (continued) • You will be given a message that the password has been changed • OR you will be given a message that rejects your new password • Passwords should be at least 5 characters long, should be something you will remember. • Your password will be rejected if it is a commonly used word or name

  15. Computer Science at UMBC • CSEE Administrative Offices • ITE 325 • CSEE Student Services Office • ITE 204 Lynn Crabb = ITE 205, Undergrad Advising • CSHC (Computer Science Help Center) • ITE 208-E 410-455-6336 In the New Building. • Linux Users Group (LUG) • http://linux.umbc.edu

  16. OIT Labs • The Office of Information Technology is responsible for all the lab computers • Labs: • ECS 021 -- PCs, MACs, SGI Workstations • ECS 005 -- SGI Workstations • ECS 104 -- PCs • ECS 104A -- SGI Workstations • ECS 122A -- PCs • ECS 333 -- PCs • ECS 336 -- MACs • Labs may be on reserve so plan ahead !

  17. OIT Labs (Cont'd) • Print Dispatch -- ECS 019 (~cents / page) • Hours of Operations • Beginning of Semester, • Monday – Friday 8:00 am – 10 pm • Saturday 8:00 am – 10 pm • Sunday 12:00 noon – 10 pm • During Semester, • Sunday 12 noon – Friday 12 midnight (24 hrs) • Saturday 8:00 am - 12:00 midnight.

  18. Consultants vs Tutors • OIT Labs are staffed by consultants • using software (pine, xrn, netscape, etc.) • some text editors (emacs, pico) • operating system commands (Unix/Linux) • Formatting / Cleaning floppy disks • communicating with UMBC computers • CSHC is staffed by tutors • Help with homework and projects • emacs and Unix / Linux questions • ITE 208-E -- Hours to be announced

  19. Logging on from Home • High speed line1: 410 - 719 - 1094 • High speed line2: 301 - 322 - 6199 • 56. k bps. • Settings for both lines • No parity, 8 data bits, 1 stop bit • On your computer, you must have • Communications software (Free CD rom from UMBC Computer Services ECS 020) • A modem

  20. telnet • Connect to your Internet Service Provider (ISP) • Windows 95/NT/98/2000 • click: Start • click: Run • Type: telnet linux1.gl.umbc.edu Login with your UMBC login- name & password.

  21. Hardware & Software Needs • Do I need my own computer? • No, but it is more convenient for you • If I have my own computer, can I use it? • Sure, but you will using it mostly to login to your GL account or for word processing • Do I need a C Compiler? • No, and if you buy one, you may be wasting your $$$. All programming should be done in your GL account.

  22. Course Overview • Introduction to Computer Organization and Architecture • Data Representation and Memory Usage • Introduction to Operating Systems • Problem Solving and Algorithm Development • Introduction to Software Engineering Using Top-Down Design • Compiling, Linking and Execution • C Programming • Reuse Based on Algorithm Selection and Design Techniques
