AND

(Or "conjunction") The Boolean function which is true only if all its arguments are true. The truth table for the two argument AND function is:

 A | B | A AND B
 --+---+---------
 F | F |    F
 F | T |    F
 T | F |    F
 T | T |    T

AND is often written as an inverted "V" in texts on logic. In the C programming language it is represented by the && (logical and) operator.
