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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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))
Some new C programming examples - files, structs, unions etc

A series of new "C" examples have been added to the web site - a course for a small group allowed me to go somewhat away from the more normal run yesterday and write some new illustrations in front of them.

Call by value v call by pointer comparison: link

Using extern to share a variable between two different sources: link and link

Handling command line parameters through pointers: link

Structures, and pointers to structures: link and link

Unions, where memory is shared between variables: link

File handling through open and read, fopen and fgets compared: link and link

And some C++ examples:

Fomatting floating point numbers in C++: link

Using a vector (in effect an object that's an array but can be extended as required: link

All examples have comments and sample outputs included and will open in a new window if you click on the links. All simple examples, and they're often the best!

This is a page archived from The Horse's Mouth at http://www.wellho.net/horse/ - the diary and writings of Graham Ellis. Every attempt was made to provide current information at the time the page was written, but things do move forward in our business - new software releases, price changes, new techniques. Please check back via our main site for current courses, prices, versions, etc - any mention of a price in "The Horse's Mouth" cannot be taken as an offer to supply at that price.
