University of Washington Computer Programming I Lecture 1 Overview and Welcome Dr Martin Dickey University of Washington 2000 UW CSE A 1 Introductory Programming University of Washington Department of Computer Science and Engineering Lecture material based on CSE 142 Computer Programming I For more information about this course www online cs washington edu A 2 CSE 142 Computer Programming I UW Catalog Description Basic programming in the small abilities and concepts Highlights include procedural and functional abstraction with simple built in data type manipulation Basic abilities of writing executing and debugging programs A 3 C Programming Language The course is taught using the C Programming Language Emphasis of course on fundamental concepts which are language independent C and C are widely used but do present hurdles for novice programmers A 4 Are you Ready for this Course You should have the equivalent of a U S high school diploma Four years of high school math through Algebra II Some background in science Good oral and written English fluency You do not need any previous background in programming You should have some basic fluency as a computer user A 5 Is This Course for You If you have never studied programming YES If you studied programming once but never used it YES If you ve learned a little HTML or Visual Basic or SQL or something else that seems like it might be programming YES If you really want to learn C or Java eventually but don t have access to a C or Java course YES A 6 Is This Course for You If you already know another programming language and just want to learn C NO If you have studied C before and want to deepen your knowledge NO If you expect that this one course will make you a programmer so you can get a job NO If your primary goal is to become a better computer user not a programmer Probably NO A 7 So What is Programming Like It s really hard to describe Many similarities to solving word problems in math Translate a problem description into a formal solution Symbol manipulation an integral part Some people describe it as puzzle solving A mix of high level creativity and low level picky details A 8 Stages of Problem Solving Ultimate goal use a computer to solve a problem Typical stages of building a solution Clearly specify the problem Analyze the problem Design an algorithm to solve the problem Implement the algorithm write the program Test and verify the completed program Maintain and update the program A 9 Focus All stages are important In this course we ignore none of them But we focus on Algorithm development Writing a program to implement the algorithm A 10 CSE 142 at the University of Washington One quarter 10 week course Course Organization when taught on campus at UW Lectures 3 times a week Quiz section once a week 5 Programming projects Done by students outside of class on their own time Two midterm exams Final exam A 11 Using the Video Lectures Not everything on the slides will be read aloud by the speaker Not everything the speaker says will be on the slides You need both And then some A 12 Beyond the Video Lectures You won t learn programming by watching the lectures as might you watch a TV program What you need in addition is Access to the slides printed or on the web www online washington edu The ability to ask questions and get them answered A textbook you can use for details and examples not in the lectures And most important hands on practice A 13 The Importance of Practice You wouldn t expect to learn to play the guitar just by watching a TV series on it There is no substitute for practice And no one can do it for you The same holds for learning to program A 14 Tips for Success Take the material in order With rare exceptions you can t skip any lecture you can t take material out of order Master each topic before continuing to the next Seek help if you get behind Practice practice practice A 15 Homework Can Be Fun Examples from previous quarters A 16 Resources UW CSE 142 Text Problem Solving and Program Design in C Hanly and Koffman 3rd Edition Addison Wesley Course Packet Slides and reference material Course Web www online cs washington edu A 17
