Overloads 1

What this C++ function overloading question tests

This is an easy C++ language-knowledge question that checks whether you can identify and distinguish between function overloads, redeclarations, and other related declarations. It's a foundational concept that matters in any C++ codebase, especially in high-frequency trading systems where precision and correctness are critical.

To answer problems like this, you need to understand the rules C++ uses to determine whether two function declarations are overloads of each other: signature matching, parameter types, const qualifiers, and return-type handling. The question rewards careful reading of code and knowledge of the language specification over guesswork.

• Function signature and parameter lists
• Overload resolution and name mangling
• Const and reference qualifiers on member functions
• Return types in overload sets
