Also since I am using this style, XCode doesn't tab in for me
when I type {

continue the

during the summer.
I learned C on Unix long before Microsoft had started producing
Windows 1.0. The first style was the first style I learned. I
believe it's called the K&R style (from the inventors of C) and it
also seems to be the preferred style in Java if you look in Sun's
Java documentation. When I then learned C++ back in 1988 (from
Bjarne Stroustrup, nonetheless), the K&R style was still the style
being used.
The first time I came across the latter style was when I had to
work on some Windows C and C++ style. I believe the style was more
or less invented by Microsoft. Most of the Unix/Linux/Cocoa code
I've worked on has used the K&R style.
I got the impression that the latter style was rooted from Pascal
(or even Algo) programmers where they usually place the "begin" and
"end" on separate lines.
If you look at an example BCPL program, you'll see the block style is
similar to the second example above, except the closing curly brace
is on the same line as the last line of the block - the mirror image
of the first example
You can d/l the BCPL reference manual that contains an example
program here:
http://www.fh-jena.de/~kleine/history/languages/Richards-BCPL-
ReferenceManual.pdf
(This manual is actually from a TYPEWRITER )
The example starts on page 29. BCPL is using $( and $) as the
equivalent of { and }
BCPL is the ancestor of B which is the ancestor of C, so this style
predates C.
