“Short Circuit Logic”

C only evaluates as much as necessary to determine the truth value.

&&The second operand will only be evaluated when the first operator is ____.

nonzero

|| If the first operand is nonzero, then the second operand is ______.

not evaluated.

~expression

replaces all the 0 bits by 1 and all of the 1 bits by 0

Bitwise AND (&)

both must be the same.

Bitwise OR (|)

at least one must be 1 for it to print 1, if same print the number

XOR ^

Only TRUE if one or the other is true but not both. One or the other but not both.
