(The guy I am > conversing with will ot take a third party definition.) The catch here is that C doesn't actually have strings, except for string literals in the source code. Strings in programs are really expectations on the part of the standard library, not part of the language itself. The definition of the standard C library contains the following: "7.1.1 Definitions of terms 1 A string is a contiguous sequence of characters terminated by and including the first null character. The term multibyte string is sometimes used instead to emphasize special processing given to multibyte characters contained in the string or to avoid confusion with a wide string. A pointer to a string is a pointer to its initial (lowest addressed) character. The length of a string is the number of bytes preceding the null character and the value of a string is the sequence of the values of the contained characters, in order." This appears in the C draft standard ISO/IEC 9899:201x (I expect it is unchanged in the current, adopted standard but this is what I've got).
