 You missed the point here, David.  I'm sure you know this, but it
 slipped past you.
 An array is base 0, meaning that the first subscript is 0.
 When you declare an array like this:
 char name[40];
 you have reserved 40 elements, the first being  name[0] and the
 last being  name[39].
 When you place anything in name[40] you have gone out of bounds.
 The NUL character belongs in  name[39].
 Does any of this ring a bell?
