The indent program can be used to make code easier to read. It can also convert from one style of writing C to another.
indent-2.2.9: description + notes
indent changes the appearance of a C program by inserting or deleting whitespace according to a plethora of options. Some canned styles of formatting are supported as well. GNU indent is a descendant of BSD indent. This file is part of the GNU indent distribution.
indent does NOT work for C++, if it does for you then you're just lucky. Don't ask for support for C++.
See the Indent home page for more information.
