What this C++ code-reading question tests

This is an easy question that asks you to trace through a C++ code snippet and predict its output. It assesses your ability to read and mentally execute code accurately—a foundational skill for any programming interview, especially in roles where you must reason about existing codebases or spot bugs quickly.

Questions of this type reward careful attention to operator precedence, variable scope, and control flow. The goal is not to run the code; it's to demonstrate that you can follow the logic line by line and understand what the program will print without compiling it. This tests both language knowledge and your discipline in avoiding careless mistakes.
