Difficulty: Medium
Correct Answer: 12, 12, 12
Explanation:
Introduction / Context: The task tests operator precedence for bitwise operators in C: & has higher precedence than ^, which has higher precedence than |. Understanding this avoids accidental mis-grouping.
Given Data / Assumptions:
Concept / Approach: Evaluate j & j first, then apply |. For XOR, evaluate directly. No parentheses are present, so rely on precedence rules (& before ^ before |) and left-to-right association within the same precedence level for | and ^.
Step-by-Step Solution:
j & j = 8 i | (j & j) | i = 4 | 8 | 4 = 12 Repeat same calculation for the second field -> 12 i ^ j = 4 ^ 8 = 12Verification / Alternative check: Compute using binary: 0100 | 1000 = 1100 (12); 0100 ^ 1000 = 1100 (12). Both confirm the same decimal result.
Why Other Options Are Wrong:
Common Pitfalls: Assuming all bitwise operators have the same precedence or that evaluation is strictly left-to-right without considering operator ranks.
