COMP 110 Introduction to Programming Jingdan Zhang June 20, 2007 MTWRF 9:45-11:15 am Sitterson Hall 014 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 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 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. About Me • UNC grad student, will start 5th year • Research interests - computer vision, machine learning, graphics • http://www.cs.unc.edu/~zhangjd • [email protected] • Sitterson 111, 919-538-4661 About You • Introduce yourself to the class - name - year - major - something special about you … Course Web Page • http://www.cs.unc.edu/~zhangjd/comp11 0/index.html • UNC Blackboard System - http://blackboard.unc.edu - Course Documents - Assignments - Checking Grades 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 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. . 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 Software • Java SDK (JDK) • jGRASP – Please install them on your laptop • See the homework 0 • We’ll do a tour later... Grades • Programming Assignments 45 % – both programs and book • • • • • Quizzes(3) Midterm Exam Final Exam Class Participation Challenge problems 10 % 15 % 25 % 5% extra 20% 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. 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/assignme nts.html 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 Late Policy • Late submission - if less than 24hrs : 25% off - if less than 48hrs : 50% off - not accepted after 48 hrs 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. 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 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 Help! • For help on general computer problems, including getting AFS enabled on your laptop or at home http://help.unc.edu 962-HELP • For help on the course related problems, ask the instructor Sending Email to me • Put COMP 110 in subject line • For example: – COMP 110, I’m lost – COMP 110, This course is too easy 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. Introduction of jGrasp Next Class • Overview of computers and programming languages • Turn in pledge form and the survey
