A Loop Without A Loop

Understanding C++ language semantics through code output

This is an easy C++ language-knowledge question that tests whether you can trace execution and predict what a program prints. These questions appear frequently in screening rounds because they quickly separate candidates who have hands-on coding experience from those who only have theoretical knowledge.

The key is to read the code carefully, understand control flow, and mentally execute it step by step. Pay attention to operator precedence, loop mechanics, and any non-obvious language features that might affect the final output. Getting the answer right requires precision—off-by-one errors or misunderstanding a particular C++ construct will lead you astray.

• Loop control flow and iteration
• Operator precedence and evaluation order
• Output formatting and stream behavior
