Bitwise And Boolean — Part 1 MCQs with Explanations

The bitwise OR operator ( | ) performs a bitwise OR operation on each corresponding bit of the two numbers. In this case, the binary representation of 6 is 110 , and the binary representation of 3 is 011 . When performing a bitwise OR, if any of the corresponding bits is 1, the result bit will be 1; otherwise, it will be 0. So, performing 6 | 3 results in 111 , which is 7 in decimal notation. Therefore, the correct answer is Option D.

The ^ operator performs bitwise XOR on the binary representations of the numbers.

The << operator performs left shift, shifting the bits to the left.

The ^ operator performs bitwise XOR on the boolean values, resulting in True.

The not operator returns the opposite of its operand's boolean value.

The not operator negates the boolean value, resulting in False.

The >> and & operators are evaluated from left to right.

The XOR operation with the same number results in 0.

Parentheses are used to indicate the order of operations.

The ~ operator performs bitwise NOT, inverting the bits of the number.

The XOR operation with the same number results in 0.

The ^ and & operators are evaluated from left to right.

The not operator returns the opposite of its operand's boolean value.

The & and ^ operators are evaluated from left to right.

The >> operator performs right shift, shifting the bits to the right.
