Exit the function early.

Understanding early function exit in C++

This medium-difficulty language-knowledge question tests whether you can trace code execution and predict output when control flow is altered by early returns. It is common in technical interviews to verify that candidates read code carefully and understand how return statements interact with function scope.

To answer questions like this, you need to follow the execution path line by line, paying close attention to which statements are reached before any early exit occurs. This skill matters in production code review and debugging—missing an early return can lead to incorrect assumptions about what actually executes.
