Course Description

This is an intensive introduction to ANSI C programming using the GNU C compiler. At the end of the course attendees should be reasonably confident in reading and writing C programs and have a good practical understanding of advanced topics such as the use of C pointers , the relationship between pointers and arrays, as well as dynamic memory allocation and memory management. In addition, they will be able to understand makefiles and version control using RCS and CVS.

Throughout, the course will emphasize a disciplined and structured approach to C programming. Debugging and code testing techniques will also be covered extensively, including the use of the GNU debugging tools. The course is not based on any particular Integrated Development Environment (IDE), and adopts a more traditional approach where files are created using a suitable editor (such as EMACS) and programs are compiled either by issuing commands at the command line, or by invoking make on an appropriate makefile.

Who Needs to Attend:

The course is for experienced programmers who will be developing applications in C++, predominantly in a Unix or Linux environment.

Prerequisites:

Attendees are expected to have some programming experience.

You will learn to:

  • Master the GNU C compiler

  • Learn both the syntax and usage of C

  • Enter the exotic world of dynamic data structures and algorithms

  • Be able to save data to files and read data from files

  • Understand the intricacies of makefiles and make

  • Appreciate the need for version control and be able to work with RCS and CVS

  • Master the techniques for writing well structured modular code in C

  • Know how to use the GNU debugger

Hands-on Exercises:

 

In addition to the major exercises listed below, the course includes numerous mini-challenges and code examples for private study.

  • Compiling a simple C program

  • Compiling an application containing several C modules (.c files)

  • Creating data structures and applications that use them

  • Traversing and processing information in one dimensional and multi-dimensional arrays

  • Finding your way round the GNU documentation and help manuals

  • Reading and writing text and binary files

  • Creating and using indexed data structures
