Which statement has the same effect as 'value = value >> 1'?

• A. value = value / 2
• B. value = value >> 1
• C. value = value // 2
• D. value = value * 2

Answer: (B)

Shifting a value right by one bit halves it, discarding the least-significant bit, when you’re working with integers. The exact same operation is performing a right shift by one bit again. So the statement that uses the same bit-shift operator with the same amount has the same effect.

Dividing by two can yield a floating result in many languages, so value / 2 isn’t always identical to a right shift for integers. Floor division (value // 2) matches only in some cases (often non-negative values) and can differ with negatives or rounding rules. Multiplying by two clearly doubles the value, not halves it.
