1. CSCI 51 Introduction to Computer Science Dr. Joshua Stough January 20, 2009

2. About CSCI 51 Learn how to develop algorithms to solve problems: –Computers do not solve problems, they implement solutions [that YOU come up with]. Learn the basic components of computer programming –can be applied to any programming language (Java, C++, etc.) Requirements / prerequisites –no programming knowledge assumed –Math, algebra

3. 6 Fundamental Concepts of Programming Variables, and Assignment (data storage) Expressions, and Data Retrieval Conditional statements (making choices) Loops (repetition) Structured data, arrays (data abstraction) Functions (procedural abstraction)

4. Is CSCI 51 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 some, you may be ready for CSCI 62 instead.

5. Course Web Pages Sakai system login: –https://sakai.claremont.eduhttps://sakai.claremont.edu www.joshuastough.com Course Documents and Schedule Assignments

6. Lecture Format Review previous material –questions Present new material In-class exercises Lecture notes are posted, but may be modified shortly before/after lecture.

7. Office Hours and Tutors M 4PM, W 3PM-on, F 3PM. All 2 nd Adams. –Door open: available, door closed: not available. Please come to office hours.

8. Software Java SDK. eclipse –on public lab machines http://www.claremontmckenna.edu/its/StudentG uide/Labs/default.phphttp://www.claremontmckenna.edu/its/StudentG uide/Labs/default.php you can install on your machine After-hours access –See Homework 0 on the website.

9. Grades Assignments40% –both programs and book Midterms 20% Final 30% Attendance and Participation10% _____________________ Total100%

10. Assignments Please submit electronic copies by 11:59PM on the due date. –turn in using Sakai assignment submission Homework assignments –practice for exams Programming assignments –budget 10-12 hours per program design, code, debugging –start early!

11. Submitting Assignments All assignments will be submitted through Sakai assignments. Submission Errors –I will email you and give a deadline for re-submitting –not checking your email is not an excuse for missing the deadline

12. Late Policy Late Assignments lose 10, 15, 25, 25, 25% for each additional day late (no credit on the fifth day). This scale may be delayed given the severity of your circumstances and my being informed of them in a timely manner. I will defer to the Counseling Center (see http://www.cuc.claremont.edu/counseling). http://www.cuc.claremont.edu/counseling If you have an athletic event and will not be able to make a deadline, you should tell me within a day of an assignment being posted.

13. Approaching an assignment Before you open eclipse and start coding (and asking for help): –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

14. Backup Your Work! Backup your work! You will lose something at some point –you might have to learn the hard way Use your U: drive (network folder). See Homework 0 if you do not have a network folder. 607-0911 ITS helpdesk

15. Collaborating You should –Struggle with the material before seeking help. –Come to office hours, email me. –Make sure you understand the solutions you receive help on, whether from fellow students or me.

16. Sending Email to me Put CSCI 51 in subject line For example: –CSCI 51, I’m lost –CSCI 51, This course is too easy

17. Eclipse and Java http://www.eclipse.org/downloads/ –Eclipse IDE for Java Developers (85 MB) –Or download from the course schedule. http://www.java.com/en/download/ See Homework 0 on the course schedule at www.joshuastough.comwww.joshuastough.com

18. Hello World example. class Hello { // main: generate some simple output public static void main (String[] args) { System.out.println (“Hello."); }
