COURSE DESCRIPTION Fall 2008 CSCI-E113 What is this course? This is a course in C and Unix/Linux programming with a focus on using C and Unix to create interactive pages for the World Wide Web. It covers in detail almost of the the C language, it introduces the major tools and ideas of Unix programming, and it shows how to use HTML forms to connect to remote databases. Who is prepared for it? We assume you know how to write computer programs. In particular, we assume you have written programs in a structured language, that you know about editors, understand the ideas of variables, loops, arrays, functions, and some data structures. If you have not written complicated programs that use these ideas in some language, you will be overtaxed by the course. Administative Details Lectures Wednesdays, 7:35-9:35, short break. Covers ideas, sample programs. Be prepared to take notes. All sample programs used in class will be stored on line, so you can retrieve them and examine and/or print them later. Several assignments, due on Saturday evenings at midnight. See course outline. Must hand in listing and sample run. Must run on the machine at Harvard. Can be developed on any machine. One midterm, one final. Homework 50%, Midterm 20%, Final 30% One hour each week, times to be arranged In the terminal room, times to be arranged Send email with any questions about the course, your homework, or reading, and we shall answer as soon as possible. See our web page for details. Questions of general interest, along with their answers, will be posted on our web site. Need name, address, phone, and section requests The required texts are C Programming, A Modern Approach by King (1st or 2nd edition), Your Unix: The Ultimate Guide, 2nd ed. by Das. A useful supplement is CGI Internet Programming with C++ and C by Felton. The Coop has them. They are for reference and additional examples. The suggested reading does not exactly follow lecture, but is pretty close. The C Programming book explains the language, the Unix book explains how to use Unix. The CGI book gives examples and explains CGI programming in more detail than the course does. The computer facilities at the Science Center are open 24 hours a day. The computers can be used via telnet/ssh over the Internet.

This is a course in Unix/Linux programming. Unix is an operating system, but it is more than just a control program for computers; it is a complete programming environment based on the idea of software tools. The Unix programming model is one of building complex, powerful solutions by combining simple, special-purpose tools. These tools are data manipulation programs. Every Unix system comes with a wealth of these tools. Tools are usually written in C. Combinations of tools are often written in a scripting language, such as the Unix shell, sh . Unix programming, then, consists of (a) designing and writing tools in C and (b) combining them using sh. Csci-e113 teaches C programming and sh programming. Where does CGI fit into this? To make your n...
