Course Description

From the Oberlin catalog course description:

This course will consider the C programming language and its relationship to the Unix operating system. It will also introduce the C++ language and focus on differences between the Java and C++ applications. Some Unix system programminig issues will also be included. The course will require a significant amount of programming.

Goals and course objectives

My goals and objectives for students taking this course are as follows:

1. Understand the role of C in the field of computing
2. Understand the interrelationship of C and Unix
3. Become fluent in C programming including
   • Compound data types such as structs and unions
   • Dynamically allocated structures (including cleanup)
   • Binary and bit-wise manipulations
4. Develop the habit of thorough testing and become comfortable in using debugging tools including gdb, valgrind, etc.
5. Become acquainted with the Unix tool philosophy and some common tools
6. Be able to write a Unix tool
7. Be able to compose Unix tools into shell scripts
8. Learn how to use C++ and how it differs from Java and C

Textbook

We'll be using the canonical K&R C textbook for this class.

The C Programming Language by Kernighan and Ritchie Accompanying website for K&R C at http://cm.bell-labs.com/cm/cs/cbook/

You might also be interested in the following books as personal references:

• C: A reference manual by Harbison and Steele [website]
• Advanced Programming in the UNIX Environment by Stevens (and Rago) [Online Copy | website]

I'll try to make a copy of these available in one of the labs for your use.

Useful Tools

There are a number of tools that may be useful to you.

Debugging

• gdb - Gnu DeBugger
• ddd - front end to gdb
• valgrind - memory checker (access and leaks)

Code browsing

Both of these can be incorporated into Vim or Emacs.

• cscope
• exuberant ctags

Useful links

There is quite a bit of useful information on C, C++, Unix, and shell scripting available online. If you find something interesting, let me know and I'll add it here.

C/C++

• http://www.cppreference.com/ -
• http://www.cplusplus.com/ -

GDB/DDD and debugging

• Guide to Faster, Less Frustrating Debugging

Unix

Shell Scripting

Humor

• C Humor

Grading

Grades will be calculated based on the following distribution:

• 50% - Homework/Projects
• 30% - Exams (probably 2)
• 20% - Final exam (not optional)

The distribution might be adjusted based on the progression of the course.

Course Policy

Attendance

Regular class attendance and participation is expected. Please talk to me if regular class attendance is going to be a problem.

Homework Assignments

There will be a number of assignments made in this class. I expect every student to attempt each assignment and turn in the results. You are encouraged to complete every assignment as this is one of the most effective ways to learn the material.

If you know that for some reason you will not be able to submit the assignment before the deadline, you should contact me in advance of the deadline. Extensions are only granted in exceptional circumstances, but need to be done in advance.

Late assignments will be penalized according to the following chart. Extra credit will not be accepted after the initial deadline.

• -10% - within 12 hours of deadline
• -20% - within 24 hours
• -40% - within 48 hours
• -60% - within 72 hours

Accommodations for students with disabilities

If you have a disability that might impact your performance in this course, or requires special accommodation, please contact me as soon as possible so that appropriate arrangements can be made. Support is available through Student Academic Services, specifically Jane Boomer. You will need to contact them to get your disability documented before accommodations can be made.

Plagiarism and Academic Dishonesty

I have very low tolerance for academic dishonesty, and will vigorously pursue available remedies for any incidents. All work in this class is to be performed according to the Oberlin Honor Code. Specifically I expect that:

1. Quizzes and exams will be closed book, closed notes, and no communication between students. This includes discussing the same to students who are taking the quiz at another time.
2. Discussion of assignments is expected and encouraged, however all work and code on assignments should be your own without outside assistance.
3. Sources should be cited including the textbook and other web sites when you use them in your work.

Illustrative examples:

1. Confirming that we had and exam is OK, telling another student in the class who has not taken it that it was easy/hard, what topics, etc. is NOT OK.
2. On a project or homework, discussing what needs to be done and how it can be done is OK, having a student (other than a TA) go over your code is NOT OK, discussing what might be wrong and how to tell is OK (and encouraged).

All assignments must include the following signed statement:

"I affirm that I have adhered to the Honor Code in this assignment."

Electronic submissions should include the honor statement in either the README file or header comments and must include your name.
