What this C++ syntax question tests
This is an easy C++ language-knowledge question that probes your understanding of how the language handles string literals, escape sequences, and console output. It's the kind of foundational question interviewers use to verify that a candidate reads code carefully and knows the standard library well.
To answer questions like this, you need to trace through the code line by line, paying close attention to how the preprocessor and compiler interpret special characters, operator precedence, and the behaviour of output streams. Small details—whitespace, escape codes, stream state—often determine the correct answer.
- String literal syntax and escape sequences
- Output stream semantics and state
- Character-by-character code reading
