One True Brace Style is a style in writing computer programs in the C programming language, and its derivatives, like C++. Also known as K&R style, named after Kernighan and Ritchie, because the examples in their seminal book are formatted this way. Also called "kernel style" because the Unix kernel is written in it. "One True Brace Style" (abbreviation 1TBS) is the name it was given by its partisans. The basic indent shown here is eight spaces (or one tab) per level; four spaces are occasionally seen, but are much less common.

For example

if (cond) {
        
}
