hello, how do u loop a pointer to a string char** something and retrieve the value ?
hello, how do u loop a pointer to a string char** something and retrieve the value ?
hmm i think i got it. u need a reference to how many items are stored within the array right?
solved thanks. a counter is needed.
Not necessarily - you could loop until the string pointed to is null.

All problems in computer science can be solved by another level of indirection,
except for the problem of too many layers of indirection.

We see this problem rise up with argc and argv, where argv is the collection of arguments stored as char** and argc acts as the counter of arguments in the char**.
Incidentally, argv also has a null pointer as its last element (i.e., argv[argc]).

Is it specified by the standard?

The C library was pretty much built around NULL terminated strings. It's silly to not use a NULL char unless you have a very sepcial reason and right now I don't know such a reason.
It's mostly safe to assume that 99% of the strings are NULL terminated.
What it has to do with NULL pointer added to the array of pointers?
