In a do-while loop, what is the minimum number of times the loop body executes?

• A. Zero
• B. One
• C. Two
• D. It depends on the condition

Answer: (B)

In a do-while loop, the body runs first and the condition is checked after that. This ordering guarantees the loop body will be executed at least once, even if the condition is false right away. After that initial execution, the condition determines whether the loop repeats. If it’s true, it loops again; if false, it stops. That makes the minimum number of times the loop body executes at least one. This also helps distinguish it from a while loop, where the condition is checked before any execution and the body could run zero times. The idea that it depends on the condition isn’t correct for the minimum, because the first execution happens regardless of the initial condition.
