If you haven’t yet read ‘Object Oriented C – Objects‘ Stop! Go Back! Go and read that earlier post before continuing. In this post I build on the earlier concepts, so much of this won’t make sense without it.
In my last tutorial, I demonstrated that it is possible to write Object Oriented code in C. I wrote some classes, and instantiated objects on those classes. I even made a start on sorting out C’s hopeless string handling (before giving up because others have already solved the problem). This time I’m going to extend the tutorial to cover Polymorphism.

I went to an excellent boarding school called Adams’ Grammar School. It was nothing like Hogwarts – in fact, to pinch an elegant turn of phrase from Guy Ellis, it was more like a Borstall run by Liberals. In the nicest possible way – I mean it fondly, and I think that Guy does too.
When we provoked the Masters or Prefects then one punishment that might have been handed down was ‘Bill’s Will’. A simple enough task, all we had to do was copy out the Will of William Adams, as laid out on the boards on the walls of Big School. Sadly, this punishment has been lost to history – a pity because it was more stimulating and educational than merely doing lines. Continue reading “Bill’s Will”
Bear with me a while. I am going to stand of the shoulders of my favourite giants (Kernighan and Ritchie, since you ask) and address an oft-made point of criticism which is levelled against my code.
The criticism? Namely that my C++ code looks suspiciously like C. There’s a good reason for this – I like C, and I’m not so keen on C++. C++ is (in my view, and with apologies to its many fans) a bad way of making C object oriented – as evidenced by the need, on occasion, to drop into plain old C in order to avoid name mangling. Objective C is object oriented C done right – but that’s a topic for another day. In the mean time, I want to address my critics by making C look like C++ – and writing an OOP program in C.

It’s been a struggle. It’s been a trial. But Innecto has now been ported to macOS. If you’ve got a Mac (any kind, as long as it’s running macOS 10.10 or newer) then you can enjoy Innecto on your desktop or laptop computer as well as on your tablet or phone. Continue reading “Innecto now ported to macOS”

The population of our country is too high, and getting higher every day. Our environmental impact is too large, and getting greater by the day. The two are connected. The more people we have in this country, the greater the impact on our scarce resources. Continue reading “What shall we do about the UK Population?”
I was very dismissive of the BBC micro:bit when I first read about it. A sub-RaspberryPi computer which cost more than the RaspberryPi Zero? Really? And if the measure of a computer’s power is what you can achieve with it, the BBC micro:bit doesn’t even stack up very well against its venerable forebear – the 1981 vintage BBC Model B. After all, with the Model B you could word process, do spreadsheets, communicate, play Elite or Exile and more besides. With the micro:bit, more memory and more powerful processor notwithstanding, you can’t do anything like as much. A bit pointless, surely? Continue reading “A Clock For Your micro:bit”
So, the ride is over – and, as you may have read in Sarah’s excellent blog post, I crossed the line having omitted only one stage (which, given the atrocious conditions with strong head winds, I don’t feel at all guilty about). Martin feels that he has unfinished business with the Newcastle to London – a point which I entirely disagreed with when I crossed the line on Sunday. Continue reading “And they’re back!”
With about five days left until the big event, I’m trying to be sanguine about my chances. Deep down I’m thinking “Oh shit, oh shit, oh shit – what have I signed up for?”, and those deep down voices are clamouring pretty loudly – making it hard for my optimistic little squeaks to be heard. I think Martin is feeling a little nervous too, although I quite like his mantra “It is what it is – we’ll give it our best shot”. Continue reading “Only 5 More Days to Go…”
