For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.

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 ...
