WebIn computer science, a Boolean expressionis an expressionused in programming languagesthat produces a Boolean valuewhen evaluated. A Boolean value is either trueor false. A Boolean expression may be composed of a combination of the Boolean constants trueor false, Boolean-typedvariables, Boolean-valued operators, and Boolean-valued … In computer science, the Boolean (sometimes shortened to Bool) is a data type that has one of two possible values (usually denoted true and false) which is intended to represent the two truth values of logic and Boolean algebra. It is named after George Boole, who first defined an algebraic system of logic in the mid 19th century. The Boolean data type is primarily associated with conditional statements, which allow different actions by changing control flow depending on whether a progr…
