1-1 CMPT 225 Data Structures and Programming Instructor: Aaron Hunter Section: E300 Campus: Harbour Centre Semester: Spring 2007

1-2 What are we doing here? “Solving problems is a practical art, like swimming, skiing, or playing the piano: you can learn it only by imitation and practice…. if you wish to learn swimming you have to go in the water, and if you wish to be a problem solver you have to solve problems.” - George Polya

1-3 The Course Data Structures –how we manage information in a useful way Programming –implementing the structures in OOP This is a programming course… but it is not a course about a particular language

1-4 Where did you come from? Many different backgrounds for this course –Java / C++ / C –Computing Science / Engineering / other Officially: –this course is language independent In practice: –this session will use Java as the primarly language

1-5 One Thing in Common You should all have taken MACM 101… unless you have special permission to skip it You will be expected to know that material when it comes up –e.g. graphs, basic logic

1-6 Topics Abstract data types –encapsulation and information hiding, public interfaces. Data Structures –lists, stacks and queues, trees, hash tables. Algorithms –searching and sorting, time and space efficiency analysis. Programming –object-oriented design and programming issues as well as recursive programming.

1-7 Evaluation Labs: 10% Assignments: 20% Midterm: 20% Final: 50%

1-8 Labs You MUST be in LAB5 –HC 7050, Wednesdays at 5:30 –can we move this? Possibilities: –later on Wednesdays? –different day –we could extend lecture to 3 hours, lab opposite day –need a unanimous decision

1-9 Labs Starting in week 2 Normally these are relatively straightforward tasks Due at the end of lab time Marked by TA, out of 4 –participation/attendance –understanding –finished work

1-10 Assignments Four assignments Tentative due dates posted on course website Larger, problem-solving type tasks –all work is individual Due at midnight on due date

1-11 Exams Midterm –Feb. 20 (tentative) Final –Tuesday April 10, 7:00-10:00 No calulators, computers, etc. Covers all readings, lecture notes, and things said in class

1-12 References Data Abstraction & Problem Solving with Java - Walls and Mirrors (2nd Edition), F. M. Carrano & J. J. Prichard, Addison Wesley, 2005 There is also a C++ version Online references will be posted on the website These notes will be posted following lectures

1-13 The Course Website All labs, assignments, notes, examples, policies, etc. will be posted there Material will generally be posted following the corresponding lecture

1-14 Assigned Readings These are also posted on the website Please read the readings before the assigned class Most readings are from the textbook, but there may be outside readings later For the most part, we will be covering the text book material in order

1-15 Harbour Centre This is the first year CMPT courses have been offered at HC So far so good… but there are some issues –limited office time –only windows machines available –exam/class conflicts can occur

1-16 Anything Else? Questions? More topics? Suggestions?
