Before we start programming we should probably ask ourselves two questions: It's pretty obvious why you'd want to program demos; because it's fun. You get all the usual advantages of doing programming, that you're learning about programming and that it's fun.

You also get the added advantage that the resulting programs are cool and nice to look at if you're good at it. And of course, demos is more fun than most other things you can program. Another good thing about programming demos is that you'll learn about many different aspects of the computer, at a very low level.

To get good performance which is very important in demosyou need to write efficient code, and the only way to do that is to bang directly on the hardware. You don't use any kind of libraries or abstractions when you program demos, you do it all the hard way.

So you need to understand how you make graphics appear on the screen, music to be heard from the speakers and how to load stuff from disk. You also need to use interrupts, which is something you really need to know about if you're ever going to write an operating system. It is also one of the things that is considered to be difficult to understand.

Don't let that scare you, though, it's a pretty easy principle to understand, and as soon as you've gotten it to work once, you can probably do it much more easily the next time.

All in all, in coding demos you learn how a computer works at a very fundamental level, and understanding that makes lots of other things in programming easier.

I'll just take one example: Well, if you've written some machine code programs you know what pointers are and that they're not dangerous 1. Why C The second question I posed above was why you'd want to program your demos on a C There are numerous very good reasons why you should use a C, some of which are applicable to some other hardware platforms as well, and some which aren't.

I'll list some of my favourite reasons here. It's a very nice processor to program. It has a simple instruction set, so it's easy to get started. It has been studied a lot and there's lots of documentation available. Of course, the only has three registers not counting the PC, SP and Status registerwhich can make it a pain in the ass to implement complicated algorithms on, but on the other hand, it sure makes you appreciate a modern RISC processor with dozens of general-purpose registers.

The VIC has a lot of interesting bugs or features, depending on how you look at itwhich means you can create amazing effects that are unique to the C It's all about learning about the hardware and learning how to use it to fit your needs, not just blindly following a specification document.

Most of these effects are achieved through well-timed modifications of VIC registers. That's one of the things are most important in demo program: Creating raster bars on the Amiga is easy: It's Old and Slow That the C is old and slow might not sound like much of an advantage, but when it comes to demo programming, it is.

It means that it's difficult to do stuff that requires lots of computations. You can't just throw CPU cycles at it, and write inefficient code.

The Linker

You have to think, to make it efficient. And doing really difficult things or rather, impossible things is what demo programming is all about. A good programmer can write a program that does something that seems very hard to do. A good demo programmer can write code that does something that is completely impossible.

That's why it's meaningless to start writing demos on a modern computer: Instead you're pushed in another direction, towards writing large programs, which will require that you use abstraction, which probably means that you'll use some high level language, and then you're not even close to programming demos.

High level languages are nice, they make it easy to create utility programs, and make them secure and robust. But if you're writing a program that displays graphics effects, that are written in a high level language, don't try to fool anyone that you're writing a demo. A demo is never written in a high level language.

Expert C Programming: Deep C Secrets By Peter van der Linden Introduction C code. C code run. Run code run please! —Barbara Ling All C programs do the same thing: look at . cloc counts blank lines, comment lines, and physical lines of source code in many programming languages. Many fail at limiting the values to the 0 to range as ASCII is a 7 bit encoding, and so far none has solved the problem that the numerical value of a character in C doesn't have to be the ASCII value!

Because a demo isn't a program, it's something else. In what way does a demo differ from a program? A demo has to take over the computer and bang directly on the hardware, it does not run under an operating system.Puterman [email protected] aka Linus Åkerlund.

The Assembler. The most important tool for assembly language programming is the assembler, the software that converts assembly language code into machine language. Given a character and we have to find its ASCII value using C program.

What is ASCII value? An ASCII value is a code (numeric value) of keys. We put the any character, symbol etc, than the computer can’t understand. A computer can understand only code and that code against each key is known as ASCII Code. Read more: What is ASCII, .
