1. CSC 213 – Large Scale Programming Prof. Matthew Hertz WTC 207D / 888-2436 hertzm@canisius.edu

2. Items to Discuss Course Goals Administration Syllabus Attendance Extra credit Late work/Make-ups Working together Grades

3. Course Goals Break down problems:  Design appropriate data structures  Develop appropriate solutions Deepen general facility in programming  Learn rigorous testing methods  Develop stronger debugging skills Develop skills for working in large systems

4. Textbook Michael Goodrich and Roberto Tamassia: Data Structures and Algorithms in Java, 3rd edition, Wiley, 2004. Yes, we are continuing to use this book  Discuss why this book is bad

5. Course Website http://klaatu.canisius.edu/~hertzm/cs c213s06 Contains lecture slides, announcements, quizzes, … Good place to check for information May not include everything said in class

6. Syllabus Detailed syllabus also on web Lectures will mix discussion of material with practices, exercises, and rockin’ good times

7. Attendance Class attendance is mandatory  Daily attendance will not be taken You are responsible for everything that happens in class Missing class is not an acceptable excuse Great way to earn a poor grade: skip class

8. Late work/Make-ups “Date due” means date due  Late work NOT accepted Make-ups will not be offered  Not needed since everyone attends class

11. Life happens When a catastrophe occurs…  Get a note from the Dean  Be prepared to show some documentation  Talk to the instructor as soon as you can We will find an workable solution

12. Help! Everyone will fall behind, not understand a detail, and/or have questions  Be mature: ask questions and seek out help  Talk to me so that I can change how I am presenting the material  Use all available resources  DO NOT leave programs to the last moment Best way to fail is to remain silent

13. Homework and Grading ItemWorth Midterm20% Final30% Homework25% Daily Quizzes10% Lab Grade15% Midterm will be given Mar. 23 th There will be more, smaller projects Daily quizzes will continue – mostly in-class

14. Homework To receive credit on code exercises:  Programs must compile  Programs must follow style standards  Programs should include some comments To receive credit on problem sets:  Programs should compile, follow style standards, include comments  Can receive significant partial credit for pseudo-code, pictures, explanations…

15. Programming Environments Continue to use any system you wish  Examples in lectures, labs will use Eclipse Link available on course web page I may be able to burn CDs as well  I really like Eclipse and recommend it

16. Style Guide Most companies have required style standards that all code must follow  Necessary for working in large systems  Makes code easier to read, follow  Limits problems when working on a team  Prevents many common errors For this semester, you get to use my style guidelines

17. Indentation Indentation is critical to writing legible code Always indent code within a set of braces Be consistent with your indentation Any guesses as the what the handout computes?

18. Braces Always use braces, even when not required by Java: for (int i = 0; i < n; i++); sum = sum + i; sumSquare = sumSquare + (i*i);

19. Braces Always use braces, even when not required by Java: for (int i = 0; i < n; i++); sum = sum + i; sumSquare = sumSquare + (i*i);

20. Increment/Decrement Operators Do not use the ++ & -- within a line // What gets stored at each line while (++k < n) { a[i++] = (2 * i) + 6; b[j] = (j++ * j) - 1; }

21. Statements Use variables to break up complex ideas // What is this computing? return ( (year % 4 == 0) && (year % 100 != 0)) || ( (year % 100 == 0) && (year % 400 == 0));

22. Statements Use variables to break up complex ideas boolean div4 = ((year % 4) == 0); boolean div100 = ((year % 100) == 0); boolean div400 = ((year % 400) == 0); return (div4 && !div100) || (div100 && div400);

23. Daily Quiz 1. Write the Node class for a binary tree 2. Give me your goals for this term: Get everyone using recursion happily Make class an enjoyable experience Beat my wife a darts

24. Coding Exercise Write a program that prints out the words to “99 bottles of beer”  Lyrics must be grammatically correct  Cannot use any fields  Cannot output anything from main() Must use other method; this method should accept a parameter Due before class on Jan. 19, 2006
