As Per Westermark noted, correctly, the ONLY one safe method is to store 
the size separately.

Another (not so safe) alternative might be to use a special array 
element, which marks the end of the array. This is something, what 
char[] arrays use: the '\0' character, but you can use whatever you 
want. BUT, this method is not really the best, as getting the size 
requires you to iterate through the array, which can be very inefficient 
at large array sizes.

So, just store the size in a separate counter, that's how most people do 
it, there's no wrong about it, actually, that's the best known method 
nowadays. You can safely use it.
