What this C++ string and character handling question tests
This is a medium-difficulty question that probes your understanding of how C++ handles string literals, character arrays, and the subtle differences in their behavior. It's the kind of question that separates candidates who have read the language spec from those who rely on intuition alone.
To answer correctly, you need to reason carefully about type conversions, pointer semantics, and what actually gets printed when you pass different forms of string data to output functions. The question rewards close attention to how the compiler interprets the code, not just what you might expect it to do.

- Implicit conversions between pointers and strings
- Operator overloading for output streams
- Array decay and pointer arithmetic
