'0' is a character. It happens to also be a number, but it's the number
that represents the character '0' in whatever encoding the compiler
uses (typically ASCII). But C and C++ both have a rule that the
representations of the characters '0' through '9' must be contiguous
and increasing, that is, '1' is one more than '0', etc. So to convert a
character that represents a digit into the value of that digit, just
subtract '0'.
