NUL -- Definition

NUL is the ASCII null character  `\0' -- i.e., the character with the value
zero.   Do not  confuse it  with the  null pointer NULL  or with  the empty
string "".  A C-language string is always terminated with a NUL.  The empty
string "" is an array of chars with only one element, namely a NUL.
