In your opinion, what is the ugliest indentation style that you've ever seen?

Question

Try to include what the style looks like in your answer so everyone else can cringe, too!

Answer 1

My favorite style is the K&R style, followed by Allman (which is how I originally learned in the 90s).

K&R:
if (x == y) {
x++;
foo();
} else {
x--;
bar();
}

ALLMAN:

if (x == y)
{
x++;
foo();
}
else
{
x--;
bar();
}

The ugliest indentation style, in my opinion, is the Banner and Pico styles.

PICO:

if (x == y) {
x++;
foo(); }
else {
x--;
bar(); }

BANNER:

if (x == y) {
x++;
foo();
}
else {
x--;
bar();
}

^ewwwwww :D
