Name
unsigned specifier — Unsigned integer type specifier
Synopsis
simple-type-specifier := unsigned

can be used with any integral type to make the type unsigned. Unsigned
integer arithmetic is always performed modulo 2
n , in which n
is the number of bits in the value representation of the integer. When
used alone, unsigned
means unsigned
int
.
Example
char c;
if (isalpha(static_cast<unsigned char
>(c))
handle_alpha(c);
