What is the difference between using (char)0 and \'\\0\' to denote the terminating null character in a character array?
(char)0
\'\\0\'
They're both a 0, but (char) 0 is a char, while '\0' is (unintuitively) an int. This type difference should not usually affect your program if the value is 0.
(char) 0
'\0'
int
I prefer '\0', since that is the constant intended for that.
