Introduction

I don’t want to start off on the wrong foot again, but I’m afraid I might have to. If you read my discussion of the C programming language you may imagine that I’d like C++. After all, C++ fixes some of C’s idiosyncrasies, adds object orientation and a whole host of new features.

You’d be wrong though. In many ways I consider C++ to be a step backwards from its parent and this piece will hopefully explain why.

You tend to find two things relating to programming languages on the Internet. The first is a long list of all the languages, often with links to a representative web site. The second category are the “representative” web sites, detailed descriptions of a particular language.

I hope to make this part of ZX81.org.uk to be the middle-ground. I won’t cover every language ever designed and nor will I cover them in vast amounts of detail. Instead I’ll look at each languages main features, advantages and flaws.

Introduction

Talking about C is not easy. Almost all professional programmers have used it at some point and many have a strong attachment to it. I don’t want to start by saying that it’s a poor language, alienating much of my audience, but I figure I’m going to end up doing that anyway so I may as well get it out of the way at the beginning.

Compared to many languages that have come since, and even some that came before, C just isn’t a very good language.

Introduction

Many developers would hate to have their master-work described as a mess, but not Larry Wall, creator of Perl and celebrity hacker. The way he sees it, the language is a mess because the problem domain — real life — is also a mess. He has a point.

I first came across Perl a few years ago when I was writing a program that required a certain amount of ‘screen-scraping’ from a telnet session, the ability to retrieve files using FTP, some complex processing and interaction with an Oracle database. This is a fairly messy problem, and one that Perl looked eminently able to solve.
