In addition to the major exercises listed below, the course includes numerous mini-challenges and code examples for private study, and to build on the skills acquired during the course. Compiling a simple C program. Compiling an application containing several C modules (.c files). Creating data structures and applications that use them. Traversing and. Suitable for: Attendees are expected to have some programming experience in a procedural language such as Basic, Fortran or Pascal. The course is also suitable for recent engineering and computer science graduates who need to "cure" any bad (programming) habits they might have picked up at University. Drive and determination are important pre-requisites as the course aims to produce competent working programmers, as is a good sense of humour (vital when working under pressure). Good.

Course programme

Overview
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 emphasise 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 commandline, or by invoking make on an appropriate makefile.

Key Skills
  • Master the GNU C compiler
  • Learn the syntax and usage of C
  • Master the principles of working with 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 SVN and CVS
  • Master the techniques for writing well structured modular code in C
  • Know how to use the GNU debugger
