Gentlemen, choose your weapons.

http://en.wikipedia.org/wiki/Indent_style

I pick: Allman style.

Downside: Proprietary AIDS -
>This style is used by default in Microsoft Visual Studio 2005 and Apple's Xcode.

int main(int argc,char **argv) {
 ...
 while(x==y) {
  something(); somethingelse(); // I'm assuming these two are somewhat related
  if(some_error) do_correct();
  else continue_as_usual();
 }
 finalthing();
 ...
}
like >>4 with 1-space indents and slightly altered spacing
