The answer
No, their performance is identical at the CPU level. The distinction is purely structural for code readability.
When to Use Do-While Loops in Algorithmic Problems
Is a do-while loop faster than a while loop?
More FAQs in When to Use Do-While Loops in Algorithmic Problems
A while loop checks the condition before running, so it might run zero times. A do-while checks the condition after running, guaranteeing at least one execution.
No, they are quite rare in standard algorithmic interviews, though they may appear in problems involving circular structures.
Yes. If the condition evaluated at the end of the loop always returns true, the loop will execute infinitely.
