This line is wrong.  The cast on the left hand side doesn't do
anything.  ss[0] is still a char type.  When you cast ss[0] to
unsigned int, the compiler would either just ignore it or put the
result of the cast to a temporary unsigned int variable and then this
temporary variable is thrown away.  Most people do casting on the
right hand side.  That is:

unsigned int result;
result = (unsigned int) (s[0] - '0');

Remember, char type is nothing more than just a 1 byte integer.
