What is uint_fast32_t and why should it be used instead of the regular int and uint32_t?
...may not be sufficient for your application.
uint32_t is not guaranteed to em>x m>ist. It's an optional typedef that the implementation must provide iff it has an unsigned integer type of em>x m>actly 32-bits. Some have a 9-bit bytes for em>x m>ample, so they don't have a uint32_t.

.... Anyway, I'll try to make it clear.
You can omit dot when using the prefim>x m>, infim>x m> and postfim>x m> notations -- the so called operator notation. While using the operator notation, and only then, you can omit the parenthesis if there is less than two parameters passed to the method.
Now, the operator n...
