- Assume the following rules of associativity and precedence for expressions: Precedence Highest *, /, not +, -, &, mod - (unary) =, /=, =, > and Lowest or, xor Left to right Associativity Show the order of evaluation of the following expressions by parenthe- sizing all subexpressions and placing a superscript on the right parenthe- sis to indicate order. For example, for the expression а +b* с + d the order of evaluation would be represented as ( (a + (b * c)')² + d)³ а. а * b 1 + C b. a (b - 1) / c mod d с. (а b) / с & (а * е / а - 3) d. -a or c = d and e е. а > b хоr c or d <3 17 f. -a + bComplete the following sentence. operators are operators that compare one or two logical values, and produce a true or false result. An example of such an operator is the AND (&&) operator. The operator in expression a && b compares the logical values stored in variables a and b. If both a and b are true (nonzero), then the operator returns a true result. Otherwise, the operator returns a false result.AcmeSoft company are either programmers or salespeople. The programmers always tells the truth, the salespeople always lie Two AcmeSoft employees A and B were sitting with a visitor in a conference room. A makes the following statement, “At least one of us is a salesperson." What are A and B?
- Compute the weakest precondition for the sequence of statements: (Statement 1) b = 2b + 1; (Statement 2) b = b-3{b < 0}Identify the logical operators you find in each of the following data structures. In some cases, they are on a single line, and in others, the behavior of the operator is implicit in the 1. code. Note: Remember that, in some programming languages, ARs are replaced by "&&" operators, ORs, operators, and, denials, by "!". a. if (X==9 AND Y=5) { Z-X+Y; b. if (X==10 OR Y=6) { Z-X*Y; } c. while (X>2) if (X==20 OR Y==3) X-X+1; Y=Y+1 d. while (Y220) { if (X NOT false) Y=Y-1; if (Y==10) X-true; e. if (X==true) { if (Y=-false) return false; } else { If (Y =true) return false; }BOOLEAN is a type of data type which basically gives a tautology or fallacy. a) True b) False
