Question
What be the output of the following pseudocode?Integer a, b, cSet a = 4, b = 4, c = 4if (a & (b ^ b) & c)a = a >> 1End ifPrint a + b + cQuestion 74AnswerA.8B.12C.24D.16
Solution
The pseudocode provided can be broken down as follows:
-
Three integer variables a, b, and c are declared and all are set to 4.
-
An if condition is set where it checks the result of the bitwise AND operation between a, the bitwise XOR operation of b and b, and c.
-
The bitwise XOR operation of any number with itself always results in 0. So, b ^ b is 0.
-
The bitwise AND operation with 0 always results in 0. So, a & 0 & c is 0.
-
Since the if condition is false (0 is considered as false), the operation a = a >> 1 (which is a right shift operation) is not executed.
-
Finally, it prints the sum of a, b, and c which is 4 + 4 + 4 = 12.
So, the correct answer is B.12.
