  1. COMP 110Introduction to Programming Jingdan Zhang June20, 2007 MTWRF 9:45-11:15 am Sitterson Hall 014

  2. What Is Programming? • Crafting a set of instructions to solve a problem • Must be clear and well-structured, analogy: cooking recipes • Ingredients (potatoes, banana, tofu, milk) • Procedures (cut, fry, stew, mix) • Results (potato banana ice cream) • Who “reads” computer programs? • The physical computer • Humans (yourself, your coworkers, your instructor) • Another computer program (Zen) • You don’t need a computer to do programming, pen and paper will do

  3. About COMP 110 • Learn how to develop algorithms • Learn the basic components of computer programming • can be applied to any programming language (Java, C++, etc.) • Is COMP 110 right for you? • Require basic computer skills • no programming knowledge assumed • Math, algebra

  4. Is COMP 110 Right for You? • Do you have web programming experience with Java, perl, php? • Experience with “classes” in C++? • Some experience with Matlab, Mathematica? • Do you know what is meant by Object, method, member variable, recursion, array, sorting algorithms? If yes to any, you may be ready for COMP401 instead.

  5. About Me • UNC grad student, will start 5th year • Research interests - computer vision,machine learning, graphics • http://www.cs.unc.edu/~zhangjd • zhangjd@cs.unc.edu • Sitterson 111, 919-538-4661

  6. About You • Introduce yourself to the class - name - year - major - something special about you …

  7. Course Web Page • http://www.cs.unc.edu/~zhangjd/comp110/index.html • UNC Blackboard System - http://blackboard.unc.edu - Course Documents - Assignments - Checking Grades

  8. Weekly Schedule • Lecture • MTWRF, 9:45-11:15 am, Sitterson SN 014 • Please bring your notebook computer • Office Hours • Before class: MTWRF 9:00-9:45am, Sitterson SN 014 • After class: MTWR 2:00-3:00PM

  9. Lecture Format • Review previous material • questions • Present new material • Notebook computers closed please • In-class exercises and programming • use notebook computer • work individually or in groups • Lecture notes are posted, but may be modified shortly after lecture. .

  10. Textbook Required Java Programming: From Problem Analysis to Program Design D. Malik Either the 2nd or the 3th edition can be used. The 2nd edition: ISBN 0-619-06497-8 The 3rd edition: ISBN 1-4239-0135-5

  11. Software • Java SDK (JDK) • jGRASP • Please install them on your laptop • See the homework 0 • We’ll do a tour later...

  12. Grades • Programming Assignments 45 % • both programs and book • Quizzes(3) 10 % • Midterm Exam 15 % • Final Exam 25 % • Class Participation 5 % • Challenge problems extra 20%

  13. Assignments • Homework assignments from textbook • practice for exams • Programming assignments • May need to demonstrate the executable code by yourself • budget 8-10 hours per program • design, code, debugging • start early! • Deadline • For assignments needed to turn in, the deadlines are due at 11:59pm on the due date • For assignments needed to demonstrate, the deadlines are before the demo time.

  14. Submitting Assignments • All programming assignments will be submitted through Blackboard • Include the demo codes • I still can not access blackboard, more details about in next lecture • All assignments must include the honor code pledge • I need signed pledge on paper. • Make it the first thing you put onto any assignment. • http://cs.unc.edu/~Zhangjd/comp110/assignments.html

  15. Collaborating • Don’t cheat! • You can • talk to each other about the lecture topics • talk about assignment requirements • work in groups during recitation on recitation assignments only • You should • do your own assignments -- design and code • You should never • talk to each other about assignment solutions • share code -- it is easy to detect and we will prosecute • Pledge Form

  16. Late Policy • Late submission - if less than 24hrs : 25% off - if less than 48hrs : 50% off - not accepted after 48 hrs

  17. Challenge problems • Beyond the the comp110 requirement • To give motivations and provide more insight in programming. • To encourage more interaction among us. • Any progress on these questions will be credited, maximum 20%. • Welcome teamwork, the gained score will be evenly distributed to team member • The problems will be posted in the next week. • Please send in your problems, let us solve it together.

  18. Before Coding • Before you open jGRASP and start coding • read the assignment • think about what the assignment is asking for • review lectures and examples on the topic • write (yes, on paper) your plan for completing the assignment (i.e., your algorithm) • talk to/email me if you’re having trouble at this point

  19. Backup Your Work! • Backup your work frequently! • You will lose something at some point • you might have to learn the hard way • Use your AFS(Andrew File System) space • use of AFS space is not required, but is recommended • you can install the AFS Client to your notebook

  20. Help! • For help on general computer problems, including getting AFS enabled on your laptop or at home • For help on the course related problems, ask the instructor http://help.unc.edu 962-HELP

  21. Sending Email to me • Put COMP 110 in subject line • For example: • COMP 110, I’m lost • COMP 110, This course is too easy

  22. Homework 0 • Install JDK & jGRASP • Sign the paper pledge form • Answer the answers in the survey • Install Download Java SDK and jGrasp • Read jGrasp tutorial and run sample Java program • Due tomorrow • If you cannot install or run JDK or jGrasp, bring your notebook computer tomorrow to the class.

  23. Introduction of jGrasp

  24. Next Class • Overview of computers and programming languages • Turn in pledge form and the survey
