C#.NET — Evaluate truth, short-circuiting, and condition outcomes for: if (age 18 && no

Question

Solve this multiple-choice question and choose the correct option.

Accepted Answer

Introduction / Context:This tests understanding of the logical AND operator && in C#, including short-circuit evaluation and the exact condition needed for assignment to execute. Given Data / Assumptions: Statement: if (age > 18 && no < 11) a = 25; Options list claims about evaluation order and when a = 25 runs. Concept / Approach:In C#, && is a short-circuiting operator. The right-hand condition is evaluated only if the left-hand condition is true. The if body executes only if both subconditions evaluate to true. Step-by-Step Solution: Analyze statement 1: "no < 11 is evaluated only if age > 18 is True." Correct due to short-circuiting. Statement 2: "a = 25 executes if any one condition is True." Incorrect; both must be true. Statement 3: "no < 11 is evaluated only if age > 18 is False." Incorrect; it is evaluated only if the left side is True. Statement 4: "a = 25 executes if both conditions are True." Correct. Statement 5: "&& is short-circuiting." Correct. Verification / Alternative check:Truth table for && confirms that the right operand evaluates only when the left operand is true and the overall result is true only when both are true. Why Other Options Are Wrong: A: includes 3 which is false. B: includes 2 which is false. D: includes 3 which is false. E: incorrect because a correct combination exists. Common Pitfalls:Confusing && with ||, or assuming both sides always evaluate. With &&, the second operand can be skipped. Final Answer:1, 4, 5
