What this C++ output-prediction question tests
This is an easy C++ question that asks you to read and trace through a code snippet to predict its output. It assesses whether you understand core language semantics—variable scope, initialization, object construction, and the order in which operations execute.
Questions like this appear in quant interviews to confirm that candidates have solid foundational knowledge of the language they claim to use. They often reveal gaps in understanding around constructor behaviour, member initialization, or subtle syntax quirks that can cause bugs in production systems. The key is to trace through each line methodically and account for how the compiler interprets the declarations and operations.
- Object construction and initialization order
- Variable scope and lifetime
- Syntax parsing and precedence
