Encapsulation
These are labeled with "extern", and should not be used.
What are global variables?
4 spaces.
What is the correct indentation for each level?
This is the naming convention for variables and static functions.
What is lower-case with underscores?
This should be placed between block keywords (such as if or while) and the parentheses.
What is a space?
This should be used to get the size of a variable type, rather than hard-coding it.
What is sizeof?
These should only include the functions, typedefs, enumerations, etc., that other modules need access to.
What are header files?
120 characters.
What is the max line length?
This is the naming convention for interface functions.
What is lower-case with underscores, starting with the module name?
This can be omitted for the following operators: * % / + -
What are parentheses?
The code should compile without these.
What are errors and warnings?
These can be placed at the top of a .c file, but better is to structure code so that they are not needed.
What are function prototypes?
Avoid these types of comments within a function.
What are block comments?
This is the naming convention for #defines and enumerations.
What is upper-case with underscores?
This is the amount of spaces that should be indented from a case statement to braces that enclose the case instructions.
What is zero?
These constants should be avoided when coding.
What are magic numbers?
All functions should be declared with this, unless they need to be otherwise.
What is static?
These should be used between operators and after commas.
What are spaces?
This is the naming convention for typedefs.
What is underscores, ending with _t?
If a break in a switch/case is not necessary, this should be used to indicate it, unless there are no statements between the cases.
What is "//NOBREAK"?
The only time when memory can be dynamically allocated.
What is initialization?
These should be organized into logically-related groups within a file.
What are functions?
These should be used to add information or highlight sections of code, but not to paraphrase code.
What are comments?
This is the naming convention for filenames.
What is lower-case with underscores?
These are the cases when braces are not needed for if or while blocks.
What is none?
This is the root of all evil.
What is premature optimization?
