So I know that you should declare char arrays to be one element bigger than the word you want to put there because of the
/0 that has to be at the end, but what about char arrays that I don't want to use as words?
I'm currently writing a program in which i store an array of keyboard letters that have some function assigned to them. Should I still end this array with
That is probably not necessary.
A null terminator is not a requirement for arrays of
char; it is a requirement for "C-strings", things that you intend to use as unitary blobs of data, particularly if you intend to pass them to C API functions. It's the conventional way that the "length" of the string is determined.
But if you just want a collection of
chars to use independently then knock yourself out.
We cannot see your code, but it sounds to me like you don't want or need it in this case.
