I would suggest it may well be easier to write good C++ if you don't
know C first. It seems that it's not quite as similar as the name
would have it, and habits learned which are reliable in C can get you
into trouble in C++ - see thread about C++ memory allocation and
dancing pointers, a few weeks back.
C is a "dirty" language. It's great for low-level stuff, bit
twiddling, messing around with hardware and stuff, which is much more
difficult in other HLLs, as well as being equally capable of the
higher-level stuff with other HLLs of the era. Assembler programmers
like C; it's been called things like "cross between an HLL and a macro
assembler". There is a certain strange beauty in writing a chunk of C
code and seeing hanging in the air beside it the opcodes for a really
neat tight bit of assembler into which the C very directly translates
(and a concomitant despair if you then have a look at what the real
compiler actually produces...) There's all that wonderful pointer
stuff, and you can write things like
switch (a) {
case 0: if (b==c) {
case 1: do_case_1();
break;
} else {
case 2: do_case_2();
break;
}
}
C programmers hate Pascal. Trying to switch from C to even a
real-world variant of Pascal with equivalent functionality - eg.
switching between equivalent releases of Turbo C and Turbo Pascal in
DOS - is *horrible*. You keep thinking "stupid bloody toy language,
can't do this, won't let me do that"... University teaching Pascal is
even worse - no string handling, no decent file I/O, no nothing much...
C++ is the bastard mongrel offspring of good old C and a bunch of
academic theoretical 80s-Thatcherite-type style gurus masturbating in
committee. Object oriented programming is cool! Strong typing is cool!
Being a programmer with short hair and a tie is cool! Meanwhile, in
the real world, more and more computers were running C code written by
long-haired C programmers who smoked lots of grass. C++, the PC
explosion and the apparent extreme fitness of OOP for Windoze-style
interfaces are all part of a plot to destroy creativity and free
thinking among programmers by getting them out of their smoky back
rooms and making them wear suits and sit in open-plan offices with
plastic plants programming boring business stuff, drinking bottled
water instead of coffee and using coke instead of grass. Reduce the
availability of jobs hacking Unix in a den somewhere, replace them
with jobs hacking DOS on PCs, but still using assembler and C. Then
introduce extensions on newer compiler versions; call it C++ and make
the syntax really complicated to fool people it's still more or less
C, but slip in restrictions more straitjacketing than Pascal. Provide
few/crappy windowing functions, so the first thing people have to do
is extend/hack/patch/write their own, and get all happy about using
the OOP features. Once they've finished sorting out the libraries and
have to write the rest of their app and find what a bummer it is cos
it's all pascally now, it's TOO LATE. They'll all be addicted to coke
and Porsches and kissing the system's arse because they're shit scared
of not being able to pay the mortgage. And they won't even notice the
plot because they'll think it's all "the march of technology".
HAHAHAHAAAAA!!!!!
With the old guard apparently neutralised, a number of factors changed
the scene from Orwellian to more Huxleian. The generation now leaving
schools and colleges had been taught from primary school to value
style over content, the Illuminati and Masons ceased to back up
Thatcher and Reagan and switched support to the Intel/Microsoft axis.
Computers became ever cheaper and more widespread; programming
environments like Windoze / Visual Basic came out, in which all the
hard/interesting work has been taken care of and programming simple
applications is a case of join the dots, point and drool and draw some
pretty pictures, but programming complex or low-level applications is
impossible, and must be left to the indoctrinated, controlled herds at
the big corps, who are instantly assigned to drawing pretty pictures
if they show too many signs of creative inspiration. To mask this,
Visual C++ came out, with the safety features added of (a) continually
crashing the entire machine, not just the task and (b) the requirement
in the jobs market to have certificates of Microsoft indoctrination.
The downhill slide accelerated with HTML, graphical browsers,
Javascript and Flash.
The flaw in this scheme was the intellectual crippling of the
programmers at the big corps, which had the inevitable result that PCs
needed to be of mainframe power to run their creations, which then
proceeded to crash all the time. This had two consequences. One was
that the remnants of the old guard and their spiritual descendants -
for creativity can never be entirely suppressed - were in an ideal
position to pour their creative energies into alternatives to the
Microsoft system, designed to facilitate rather than obscure the art
of coding for them, similarly to facilitate the solution of problems,
and not to crash all the time. Foremost among these was one Linus
Torvalds, who created the kernel known as Linux that finally broke
the Microsoft dependency and enabled the spread of a free, Unix-like
operating system. The further dependency on Intel was broken by the
Debian Project who took an interest in porting Linux to as many
different architectures as possible.
The other consequence was that bored teenagers who used to hang around
in the streets and smash up bus stops, now hung around in their
bedrooms with computers, which they used to electronically smash up
other people's computers. The poor quality of Microsoft software made
this laughably easy, and viruses, worms and other pathological
software proliferated rapidly. Their spread was helped by the strategy
of keeping people as ignorant as possible about the workings of their
computers, so they were long unaware of infection and passed it on
widely.
An early indication of the potential consequences of this situation
was the major power blackout in the US which, it was eventually
leaked, had been caused by a virus attacking the Microsoft systems
used by the power distribution network; the leak itself was caused by
a second virus broadcasting random documents from the company's
internal network to random email addresses. Shortly after this the
White House was severely damaged when computers controlling the sewage
network succumbed to viral attack, pumps went into reverse, raw sewage
pumped out of toilet pans and the accompanying methane exploded. The
President, fleeing the foul flood, was hit by a fragment of flying
debris; fortunately for him, it hit him in the ear, and so was able to
pass through and out of the other ear with minimal injury. In the same
week the 'Shining Sun' virus, which exploited a flaw in certain
laptops to turn up the power to the screen backlight to dangerous
levels, achieved notoriety in the UK when the backlight in Tony
Blair's laptop exploded, knocking him unconscious into the Thames; he
was only saved by the buoyancy of his cranial airspace.
The tide really turned in Russia after an exploit against Microsoft
Powerpoint caused Vladimir Putin's presentation to the United Nations
to inform the assembled delegates that their mother was a hamster and
their father smelt of elderberries. A purge on all Microsoft products
followed and several million Windoze CDs were ceremonially burned in
front of the Kremlin. Bill Gates despatched himself to Russia to try
and restore Microsoft's fortunes; his limousine stalled on a level
crossing; the driver escaped, but the rear doors apparently jammed and
Gates was crushed by a train. Within months every computer in Russia
was running Linux, computer dysfunctionality dropped to minimal levels
and the effect on Russia's economy was such that the West was forced
to follow their example. The change was slow initially, but once
enough Western organisations had installed Linux that its success was
shown to be no peculiarity of Russia, market forces did the rest, and
Microsoft disintegrated.
Oops, sorry, we haven't got that far yet...
