Actually the standardization of C sparked huge debates in the early
90's. There were lots of minor changes and one big style change that
really polarised opinions. In traditional C you defined a functions
parameters like
int foo()
int a;
float b;
{ /* body here */ }
Oops, a slight mistake there it should be:
int foo(a,b)
int a;
float b;
{ /* body here */ }
I started with c in the 1980s using Mix Power C under Microsoft DOS 3.5.
I still have my Mix C compiler and manual (It runs under dosemu in Linux
:-), but mine was not "Power C"... and it came in dual CP/M
and MS DOS versions (I had a CP/M Computer too at the time). So I'm
guessing Power C was their ANSI version. I used it for years because I
could carry the whole thing, including IDE, on a single 720K floppy disk
- remember them! :-) Very handy for writing a quick ad-hoc tool
on a customers site. Exactly the kind of thing I use python for nowadays!
different from the K&R specs. Interesting!
Other differences included the introduction of
const for constants, the void type, and the // style line comment.
A lot of previously undefined behaviors became defined too. And the
library was expanded beyond all recognition, bringing in lots of
features that had been implementation dependant into the standard.
