    QUESTION 2 Boolean or "truth-valued" expressions are how we express conditions that control choices and repetition in computer languages. Consider the following Python Boolean expression, where variables alpha, beta, and gamma are of type Boolean: alpha and (beta or gamma) In any algebraic notation there are usually several different ways of writing the same expression. For instance, in integer arithmetic the value of expression '4 x (5 + 2)' is numerically equivalent to that of expression '(4 x 5) +...

    In this lab we are building a handful of functions to perform Boolean operations. These operations are performed upon Boolean variables. A Boolean variable is either true or false. Boolean operations return Boolean values. There are only two Boolean values, either true or false. Sometimes true is defined as 1 and false is defined as 0. Build functions in C, C++, Java or Python to support the following five Boolean operations: Logical implication Logical equality Exclusive disjunction Logical NAND Logical...
