You have to know how long the strings you intend to store will be.

Yes.

Padding could be either of two things. A) paranoia, or B) for data
alignment -- some processors require certain types of data to be
on even addresses only, or some other requirement. Usually the
compiler will take care of that for you.

If you say char[8], you have 8 "cells". Their numbers will be from 0 to 7.

You need a "cell" for each byte you intend to store. This includes
the NUL char string terminator. Whether you need to add one to
the 8 given depends upon whether you data will be 8 chars long
(in which case you need 9 cells) or whether your data will be 7
chars long (in which case 8 -- 7+1 -- is proper). I don't know
what your data lengths will be, you have to answer that yourself.
