Ascii

What do the integer 0 correspond to in ascii and unicode? :confused:

Can i use the integer 0 to "terminate" my char[] inputbuffers? :confused:

ASCII table

not sure about your second question though.

you can terminate with '0' when you write your own functions who do the right thing then.
some functions accept a delimiter symbol (i think it was read and write (stream io)) .
basically it depends on how a function "interprets" a symbol. if it interprets it the way you expect it to interpret then its ok. problem arise when there are differences between what the function does and what you excpect it to do :)

note that you dont need to terminate arrays.
but all string functions of the c library expect strings to be terminated by a '\0' character.

0 is an int. '0' is the char zero (or maybe the char capital Oh, I can seldom tell the difference). '\0' is the char representation of the null char. Therefore 0 and '\0' can be used interchangeably.
