Reassigning a data batch

Understanding object reassignment and memory behavior in C++

This is a medium-difficulty C++ code-reading question that tests your grasp of how assignment operators and object lifecycles work in practice. You'll need to trace through a code snippet and reason about what actually gets printed, which requires understanding the difference between shallow copying, deep copying, and how modern C++ handles resource management.

Questions like this appear in technical interviews because they reveal whether you can predict program behavior without running it—a critical skill when debugging production systems or reviewing code under time pressure. The question rewards careful attention to object state, constructor/destructor calls, and the semantics of the assignment operator.

• Copy semantics vs. move semantics
• Resource ownership and cleanup
• Operator overloading and default behavior
• Object lifetime and scope
