 Simple loop counters (i,j,k) don't need to adhere to this style.

 Naming for parameters that are being modified (eg. OUT):
 It is recommended (but not mandatory) to use a suffix of OUT or '_', eg:

+Braces should be formated with Allman Style (opening brace on separate line) and NOT K&R style (opening brace on same indentation level as its header).
