For functions declarations, K&R style says braces open on new lines.

it is a sure-fire way to distinguish between developers who learnt to code a while ago from K&R and those who didn't.

I can't stand looking at braces on new lines. It is all from back when a new line was something to be treasured as displays were bad.

Actually, my copy of the second edition K&R seems to have the opening brackets on new lines when it comes to function declarations, so:

main () {

but: while (){ and: if(){

I don't have a copy of the first edition at hand but I seem to remember that it uses this same style.

The first edition has opening brackets for functions on a new line. It also used a space before parenthesis for while loops and conditionals. Return types, when required, were on the same line as a function name.

Exactly. On a 24-line VT100 display, you bet that every line was important!

As should we all.
