A "logical
AND
" is true if and only if both its operands are true, while a
"logical
OR
" is true if and only if either of its operands are true. The "ex-
clusive
OR
" operator yields true if either, but not both, of its operands is
truewhich is the same as testing the equality of the two operands, so we
can rewrite our earlier example as:
if ((x < 0) ^ (y < 0))
differentSign();
else
sameSign();
The unary operator
!
negates, or inverts, a boolean, so
!true
is the same
as
false
and
!false
is the same as
true
.
Boolean values are normally tested directlyif
x
and
y
are booleans, the
