Infinite Range with Termination

What this C++ language-knowledge question tests

This is a medium-difficulty question about C++ semantics and undefined behaviour. It requires careful reading of a code snippet to predict its output—a skill that matters in production systems where subtle language details can hide latent bugs.

The question probes your understanding of how C++ handles certain constructs, their scope, lifetime, and how the compiler or runtime processes them. Interviewers use questions like this to assess whether you reason precisely about code behaviour rather than making assumptions, and whether you can spot potential pitfalls that might cause crashes, hangs, or unexpected results in real trading systems.

• Scope and variable lifetime
• Compiler semantics vs. runtime behaviour
