Understanding do-while loop behaviour in C++

This is an easy language-knowledge question that tests your familiarity with the semantics of the do-while loop construct in C++. It is the kind of question used to establish baseline competency with control flow during screening rounds.

The key distinction between a do-while loop and a standard while loop lies in when the condition is evaluated. Understanding this difference — and being able to trace through code execution carefully — is essential for writing correct programs and debugging unexpected behaviour. This question rewards careful reading of code over memorisation.

• Loop condition evaluation timing
• Guaranteed execution of loop body
• Exit conditions and control flow
