Thing is I can know if the necessary information is provided (i.e. CPU architecture, version of the standard). Portability is a feature of C, but C's portability is mostly syntactic and only partly semantic.

- gkya 10y agoI don't really want to be a pedant here, but in this case if the necessary information was provided, I had the knowledge to find a correct answer. This is different from the case where even if the information was provided I wouldn't be able to know because I don't have the necessary knowledge.
