For example, if we might attempt to assign
the value 336 to an 8-bit signed char,
the actual value assigned will be 80,
because 80 is equal to 336 modulo 256.
9 The range of nonnegative values of a signed integer type is a subrange of the
corresponding unsigned integer type, and the representation of the same value in each type is the same.31) A computation involving unsigned operands can never overflow, because a result that cannot be represented by the resulting unsigned integer type is reduced modulo the number that is one greater than the largest value that can be represented by the resulting type.
