Course Objectives

This course is an introduction to C programming using the Unix operating system. The course is designed for individuals who understand programming constructs and concepts in another programming language. No prior Unix experience is necessary. Students will develop a proficiency with Unix and the C programming language that will be helpful for upper-level courses, particularly CSC 432, Operating Systems. Topics to be covered include basic C syntax and program structure, separate compilation, functions, structures, pointers, and memory management. Unix tools including the Emacs editor, the Make utility, the GNU C compiler, and the GNU debugger will be used.

Prerequisites

Texts

The required text for the course is The C Programming Language, 2nd Edition (Prentice-Hall, 1988, ISBN 0-13-110362-8) by Brian W. Kernighan and Dennis M. Ritchie. This is available from the Saint Rose Bookstore (and elsewhere). If you buy elsewhere, be sure to get the correct edition. It's a handy book for any computer scientist to own, so think of it as an investment.

Lectures/Labs

This course is organized as a series of self-scheduled lab exercises that are to be completed in sequence during the course of the Winter Immersion period. These labs as well as supplemental readings are listed on the lab and reading schedule. There, you will find a link to a web page for each lab highlighting the lab's topics, listing class examples, and the new assignment along with the latest recommended dates of completion.

Your submissions for lab assignments will include several types of items. Different requirements apply to each, as described below. It is important that you adhere to file format and naming requirements to facilitate grading. Submissions that do not meet these requirements will not be accepted.

Lab Questions
The answers to all "lab questions" for a particular lab should be included within a single plain-text file named labn.txt, where n is the lab number. The file should start with your name and the lab number, followed by line-wrapped text responses to each lab question in the assignment. Your file should be appropriately line-wrapped for easy reading in a window or on a printed page with a width of 80 characters.

Note: for lab questions that ask you to draw a memory diagram, you have a few options. You may attempt to represent the memory with plain text, but that is difficult to construct and read. Ideally, you would use a drawing program and submit a PDF file, but you are also permitted to draw the diagram on paper and submit a scan or photograph, as long as the diagram is legible in that form.

Output Captures
You will sometimes be asked to capture the output of an existing Unix command or one of your programs in a file for submission. The file name to use for each such task will be specified in the question.
Practice Programs
Your submissions for practice programs are graded primarily on correctness, but you will be required to include your name at the top of the program, and you must use the file name specified.
Programming Assignments
These are the most formal submissions and will be graded on design, documentation, style, correctness, and efficiency (where appropriate). A good design will use an appropriate algorithm, data structures, and language constructs to solve the problem. A well-documented program will include a comment at the top of each file that includes your name, the assignment, and a description of the contents of the file. There should also be comments for each structure definition, each function definition (including a brief description of the function's purpose, its parameters, and return value), each variable or group of related variables, and any section of code whose purpose and/or behavior is not obvious from context or the code itself. Style requirements include appropriate formatting (sufficient and consistent indentation, spacing, and punctuation, wrapping long lines of code), good use of constants, and meaningful and appropriate names for variables, functions, constants, and parameters. Correctness, of course, requires the expected output be produced for a set of test inputs (which will normally not be provided in advance). Efficiency will be more important in some assignments than others, and requires that the program does not do any unnecessary computation or use any more memory than needed. This includes returning memory to the system when using dynamic memory management. And, of course, you must use the file name specified.

You are strongly encouraged to develop your C programs using a genuine Unix environment (the Saint Rose Macintosh and Computer Science Linux systems or your own Macintosh or Unix/Linux system). If you choose to develop your programs anywhere than the Saint Rose Macintosh and Computer Science Linux systems, it is your responsibility to ensure that your program works on the grading platform.

As there is no fixed schedule, there are no late penalties, but all work must be submitted before our final exam meeting. The recommended dates for completion of each lab lead to a very intense 16-day schedule, running into the first week of the spring semester. It is recommended that you begin sooner and stay well ahead of that schedule. Note that as a 1-credit online course, the expectation is for a minimum of 45 hours of effort to complete the work. Some may be able to finish in a shorter total time, but as with any task that involves programming, the time needed could be significantly longer in some cases.

All assignments are to be submitted electronically unless otherwise specified. Keep a copy of all submissions for yourself.

Exams

There will be one exam: a final exam at 9:30 AM on Friday, January 17. Details about the exam will be made available as it gets closer. You should plan to complete all of the labs before this date, as it cover exactly those things you learned about and practiced in the labs.

Grading

Grades for individual assignments and exams are not scaled. Any scaling deemed appropriate will take place at the end of the semester by adjusting the thresholds. The following thresholds may be adjusted downward (thereby raising grades) but will never be adjusted upward.

Breakdown:

Scale:
Labs 66.67% A >= 93% A- >= 90%
Exam 33.33% B+ >= 87% B >= 83% B- >= 80%
C+ >= 77% C >= 70%
D >= 65%
F < 65%

College policy forbids changing of course grades after they are submitted except in very specific cases (such as an error in grading of an assignment or in computation of a grade). Any such errors that slip through must be found and rectified quickly after grades are submitted. In rare circumstances, a student request for an incomplete grade may be approved at the discretion of the instructor. Requests must be made one week prior to the end of the semester, and terms of such arrangements must be mutually agreed upon before grades are submitted.

Disability Accomodations

If you are a student with a documented disability and require academic accommodations please register with Lynn Cantwell, the Director of Services for Students with Disabilities, located in the Academic Support Center on the 2nd floor of St. Joseph Hall (campus extension 2335 or 518-337-2335, off campus) for disability verification and for determination of recommended reasonable academic accommodations. After you have made arrangements with that office, please see me to discuss your accommodations. Please remember that timely notice will help avoid a delay in your receipt of accommodations.

Academic Integrity

You are encouraged to discuss the concepts related to course assignments and exams with your classmates. This is an essential part of a healthy academic environment. However, work submitted for grading must be your own (or the combined work of group members, for group assignments). Any unauthorized copying or collaboration is considered a breach of academic integrity and will not be tolerated. Academic dishonesty cases are unpleasant and uncomfortable for everyone involved. You are responsible for reading and understanding The College of Saint Rose Policy on Plagiarism and Academic Integrity.

The minimum penalties for a first violation will include failure (0 grade) for the assignment or exam in question and the filing of a Academic Dishonesty Report Form with the Registrar's office. A second violation will result in failure of the course and a second Academic Dishonesty Report Form.

If there is any doubt about the degree of collaboration allowed or the permitted sources for a particular assignment, please ask for clarification before collaborating or consulting the source. Any such collaborations or sources must be cited properly.
