Introduction

This chapter is a partial reference manual for the C language and the standard C library, concentrating on the parts likely to be useful to mathematics undergraduates writing programs for the CATAM projects, using computers on the University PWF, and emphasizing the differences between C and Pascal. The code extracts in the chapter do not use the CCATSL functions but can be compiled with the gcc software supplied with CCATSL - see the CCATSL on-line info.

Although some features of the PWF setup will not be shared with C compilers in general, this will be hilighted in the text, and most of the information will probably be useful to students programming in C on other systems.

This is not a tutorial, and users new to C and to CCATSL are strongly advised to seek out the `Green Book', Learning to use C and the CATAM Software Library, by Dr C. D. Warner, which gives a gentle introduction to both the C language and the CCATSL library.

Less importance aspects of the language will not be covered, and we will refer the reader to a proper reference like:

The C Programming Language by B. W. Kernighan and D. M. Ritchie, Prentice Hall.

Another book on C which may be helpful is:

A Book on C by Al Kelley and Ira Pohl, Addison-Wesley, fourth edition.
