Imagine writing a drawing program before objects if you want to draw a circle on the screen, you use a function for drawing circles. Smalltalk allowed the programmer to describe all kinds of things – shapes, sounds, video – as objects. Before Smalltalk, languages dealt largely with strings and numbers. Smalltalk was the first successful object orientated language. C has also influenced other computer languages Visual Basic now looks very like C.

The influence of C has spread with the influence of UNIX most applications throughout Windows/Linux/Mac OS are written in C, C++ or C#.

These don’t mean much unless you’re a programmer! But essentially, they stop the language getting in the way of what the programmer is trying to achieve.

Some of the key features of C include extendibility, close coupling with the hardware, fairly strong variable typing and function pointers. C is a small language and therefore easily learnt and easily ported to different operating systems – C compilers are usually written in C. Pretty much the whole of UNIX and applications that run on UNIX are written in C, or C derived languages (C# or C++). Simu-Double2TypeC is the language of UNIX, C was written by Dennis Ritchie in 1972.

Pictured above is the terminal on my Mac OS X machine which gives you access to the underlying UNIX system. Apple’s Mac OS X is based on UNIX (BSD to be exact), and most developments in modern computing (virtual desktops, virtual memory spring to mind) start on UNIX. UNIX (and its modern derivative Linux) is a programmers dream – it doesn’t get in the way too much, has powerful editors, good compilers, is very adaptable and, probably most importantly, a world-wide community of fans and users. This is because UNIX was essentially written in a high level language (of which, more below). UNIX had the advantage of CP/M that it could fairly easily be ported to different machines, but it wasn’t particularly dependent on the hardware – CP/M needed a 8080/Z80 processor, UNIX can generally be run on anything from a phone to a supercomputer. Ken Thompson was the bright guy and he, essentially, developed the first version of UNIX (then called Unics) to make a game run faster. Picture 5-6UNIX shows the advantage of giving bright guys some time and money. Emacs is one of the two main contenders in the traditional editor wars, the other being vi. Virtually all programming languages provide an environment now. EMACS can be configured to “know” about the format of different languages, keywords are shown in different colors, function parameters are shown automatically – it’s changed how programmers program. Essentially the programmer always worked in EMACS the program was edited, a single keypress would compile and link it. The compiler and linker was still there, but the process was hidden. EMACS was (and is) an editing system for the UNIX operating system and provided the first programming environment. In the early days of small computers, programs were written using text editors, and then the program files were processed through compilers and linkers to produce a finished program. Having a single operating system made it possible for applications such as Wordstar to flourish.

This concept made it simpler to “port” – the process of adapting software so that an executable program can be created for a computing environment that is different from the one for which it was originally designed.

So he separated out the machine-dependent parts of the operating system (the disk controller and serial input/output) into a small subsection (the BIOS), the bulk of the operating system left unchanged. Gary Kidall was working at Naval Research labs on an operating system and wanted to continue work at home on his own home-built computer, but the machine at work was too different. CP/M was something of an accidental invention.
