This last line raises several questions. Firstly, C-strings have an
implicit nul-character at the end so no need to explicitly try to add
one there. You also don't need to have an explicit size between the
square brackets since this is automatically calculated if you do
initialization upon declaration. Why isn't this static? Why isn't it
const? Would a simple define make more sense instead of a dedicated
variable?
