- Indent with tab of width 8. - Use four column to indent continuation line. - Fold long line if possible. - Use return (xx) instead of return xx. - Compare pointer against NULL instead of testing like boolean. - Delete whitespace at the end of line. - Delete whitespace in front of function call operator. - Delete whitespace after cast. - Dereference a pointer to function explicitly. - Add an empty line after local variable declaration. - Use NULL instead of (char *)0. - Dont use block for single statement.
