For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
C and C based languages module C221
Secure C Programming
Exercises, examples and other material relating to training module C221. This topic is presented on public courses Learning to Program in C, Learning to program in C and C++, Programming in C, C and C++ Programming, Learning to program in C and C++, C and C++ Programming

As a low level language, there are a number of things that C does NOT do for you that other languages do. For example, if you use the contents of an uninitialised variable you'll get unpredicatble results, and if you reference off the end of an array you'll use or corrupt other variables or your code. Such issues, together with bad programming and a lack of thorough testing, have caused some of the major internet security holes we've seen over recent years. In this module, we study the issues that you need to guard against and teach you how to write robust and reliable code in C.

4635Encapsulating logic in functions and structs - the C approach to Object Oriented techniques
Although C is not what is described as an "Object Oriented Language", many of the good programming principles that are applied naturally in OO programming can be applied in C too. I wrote an example that showed this yesterday - with a C struct defining what is in essence an object, and being referenced ...
