1. COMP 110 Introduction to Programming Jingdan Zhang June 20, 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 5 th 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/comp11 0/index.htmlhttp://www.cs.unc.edu/~zhangjd/comp11 0/index.html UNC Blackboard System - http://blackboard.unc.eduhttp://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 pledgepledge –I need signed pledge on paper. –Make it the first thing you put onto any assignment. http://cs.unc.edu/~Zhangjd/comp110/assignme nts.htmlhttp://cs.unc.edu/~Zhangjd/comp110/assignme nts.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.edu962-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 surveysurvey –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
