INFSCI 0012 - Introduction to Programming

(Fall 2004, CRN 27655)

[ Formal Data | Course Tools | Syllabus | Course Books | Course Schedule | Course Materials | CourseWeb | KnowledgeTree ]


Course Objectives

  1. To understand the nature of programming as human activity
  2. To learn and experience main components of programming process
  3. To understand main control structures of procedural programming languages
  4. To learn and being able to use major programming patterns
  5. To understand the principles of data storage and manipulation
  6. To get prepared for the more advanced programming courses such as IS15 and IS 20

Upon satisfactory completion of this course, students will be able to write small meaningful C programs that includes major control structures (such as loop, selection), programming patterns (such as maximum or sequential array processing), and data types. On the way to that goal we will have to learn a reasonable subset of C language, explore many working examples and write multiple C programs.

Important note: The Introduction to Programming course is targeted to the students who have no or very little programming knowledge and experience. The goal of this course is to get you familiar with programming concepts and constucts at a relatively slow pace. To help you in gaining programming skills we use a number of special educational tools and systems. After IS12, you should be ready to take IS15 even if you were a complete novice. Students with some good programming background may find this pace boring and are strongly advised to proceed directly to IS15. IS12 is not a required course. If you have any doubt, scheck the course overview below and the Course Materials page to see what exactly will be taught. Vice versa, the students who experience problems when taking more fast and steep programming courses such as IS15 are strongly advised to take IS12 first.

Expected Course Load

Programming courses are traditionally among the hardest and most time consuming courses. You will have to do a lot of work each weak to follow the course: do your readings, run and explore program examples, solve programming exercises and homeworks. To help the complete beginners to master the subject, we have provided several learning tools. These tools do help a lot to those who use them - but it also requires time. To be on the safe side, plan to spend at least 6 hours outside of the classroom each week for this course. If you have some programming background, you may need less than 6 hours. However, some students may need more than that. Note also that you need to invest your time regularly. Almost every lecture is build upon material presented in several earlier lectures. A failure to comprehend just one lecture may get you out of track for the rest of the course. If you have too many other commitments this semester to allocate enough time every week, consider taking this course later.

Assessment and Grading

Components of the Final Grade

Course assessment includes quizzes that will be offered through the course, homework programming assignments, and two exams - midterm and final. The final exam is not cumulative. You final grade has four components: class attendance, work over the duration of the course, midterm exam grade, and final exam grade. Grade for the work over the duration of the course is a sum of your assignment grades, quiz grades (we will about 10 C quizzes, but the lowest quiz grade will be excluded) and extra credit points. A value of a 5-questions quiz is 5 points. A value of a homework assignment is between 6 and 12 points (depending of the complexity of the problem). The value of each exam is 100 points. Exam grades will be scaled to adjust to the class performance.

Your progress will be measured as a percentage of the max possible points: (attendance_points + homework_points + quiz_points + extra_credit_points + exam_points)/(max_attendance_points + max_homework_points + max_quiz_point s+ max_exam_points) * 100%. Using this formula you can always check where you are standing. Score < 50% corresponds to F, 50-62.5 is D range, 62.5-75 is C range, 75-87.5 is B range, and 87.5-100 is A range. Lower and upper parts of each range corresponds to - and + modifiers.

Extra Credit Points

You can earn extra credit points for several things such as asking a good question in a discussion forum, providing a helpful answer in a discussion forum, helping during the lecture, attending additional "catch-up" sessions, finding errors in slides and examples. Extra credit points will be added to your assessment/quiz results and can compensate missed your points. You can earn up to 15 extra credit points, however, together with these points, your can't earn more than max_homework_points + max_quiz_points for the work over the duration of the course.

Submitting and Naming

All assignments has to be submitted in paper form on the due date before or after the lecture. Submit a printed copy of the program code and (for C part of the course) a sample output. If you submitting the paper version after class, please, bring it to the instructor's office or slide under the office door by midnight. In addition, the program code of the assignment in text (ascii) format has to be submitted electronically using CourseWeb's dropbox at any time by or on the due date (your submissions are time stamped!). Naming conditions for electronic submissions are strict. When submitting via the dropbox, the link to your file should be named programX where X is the assignment number. You will lose 0.1 pt for every misnamed link starting from assignment 3. All submitted work should bear the number of the assignment/quiz and the author's name in printed form inside the header comment. You will lose 0.1 point for every solution that lacks the header comment with this data. By submitting work under your name, you are indicating that you have completed the assignment. This means that you should be able to completely explain every line of code in your program. Failure to be able to account for your coding decisions will be reflected in your grade.

Course Policies

Academic Integrity

You are expected to be fully aware of your responsibility to maintain a high quality of integrity in all of your work. All work must be your own, unless collaboration is specifically and explicitly permitted. You are welcome to discuss the solution of programming exercises that are not graded. You are even encouraged to do it within study groups and using CourseWeb discussion forums. For graded homework assignments the only acceptable collaboration is to discuss the algorithm (the idea) of the solution. No collaboration on the level of program code is permitted. Every student has to write own program solution from the beginning to the end. You should not view or copy the code written by other students, neither should you share your code with others.

Any unauthorized collaboration or copying will at minimum result reducing credit for the affected assignment (50% for the first case, 100% for further cases) and may be subject to further action under the University Guidelines for Academic Integrity. You are expected to have read and understood these Guidelines. A document discussing these guidelines was included in your orientation materials.


Class attendance is a component of your grade (each lecture worth 1/2 point). We will record the attendance at every lecture. To reach 100% attendance you will need to attend any 20 lectures (max_attendance_points=10). You can skip lectures over this number without affecting your attendance score. While most of the material covered by the lectures could be found in course books, for most of the lectures the order of presentation does not match any book exactly. Some material is not sufficiently covered by the book. Finally, all lectures include animated demonstration of examples.If you have missed the lecture, make sure you have a copy of the slides. Spare copies can be picked up from a folder near the instructor's office or printed from the Web.

Late Submissions and Resubmissions

The due date for assignments is strict. If either a dropbox or a paper version of your homework solution is submitted after the due date you will lose 20% of your score for each late day. I.e., homework submitted one day after the deadline will bring you only 80% of earned points; two days after the deadline it will bring you 60%, etc.Weekends, holidays, or break days are not counted as late days. No assignment can be submitted after it was analyzed during the lecture.

You can also improve your submission or fix errors in your submission until the due date. Simply upload the new version adding "_v2", "_v3", etc to the name of the link to the program (i.e., program3_v2).


If you miss a quiz or and assignment, you will receive a zero. There will be no make-up quizzes, but the instructor will drop one lowest quiz score. There are also no make-up assignments since most of the assignments will be analyzed in the class shortly after the due date. Missed exams can be made up in cases of extreme circumstances.

Office Hours

Office hours are an opportunity for you to clarify details you may have missed in class or to resolve a serious problem you have encountered when working on an assignment. They are not a place to get a "second run" of the lecture if you missed the class or obtain answers on the assignment. If you come to office hours with a programming problem, make sure that you have access to an electronic version of your code (use dropbox or bring a floppy). If you are not able to attend office hours due to your work schedule, you can arrange an appointment with a GSA or the instructor.

Special Considerations

If you have a disability for which you are or may be requesting an accommodation, you are encouraged to contact both your instructor and Office of Disability Resources and Services, 216 William Pitt Union, (412) 648-7890 / (412) 383-7355 (TTY) as early as possible in the term. DRS will verify your disability and determine reasonable accommodations for this course. If you would like any additional information, please take a look at: http://www.drs.pitt.edu
