Do...While loop runs:

Do...While loop runs:

• A. A block of code that runs while a condition is true but runs at least once regardless of whether the condition specified for the loop is true
• B. A block of code that runs only if the condition is true before the first iteration
• C. A block of code that never executes
• D. A block of code that runs exactly twice

Answer: (A)

Do-while loops are post-test loops: the block runs first, then the condition is checked. Because the condition is evaluated after the body, the code inside the loop will execute at least once, even if the condition is false on the first check. If the condition remains true, the loop repeats; if it becomes false, it stops. This matches the description of a block that runs while a condition is true but runs at least once regardless of the initial condition. The other possibilities describe different looping behaviors: a pre-tested loop may skip entirely if the condition is false before the first execution; a loop that never executes isn’t possible here; a loop that runs exactly twice would require a fixed iteration count, not a condition-driven post-test structure.
