Mastering C++: A Comprehensive Quiz Based on 'Thinking in C++'

C++ uses a technique called name mangling to handle function overloading. This means that the compiler will give each overloaded function a unique name based on the combination of argument types. This way, when the code is compiled, the compiler can distinguish between the different versions of the function and call the correct one based on the argument types passed in. Option A is incorrect because changing the return type does not determine if a function is overloaded or not. Option B is incorrect because the inline specifier is used for optimizing code, not for function overloading purposes. Option D is also incorrect, as C++ does support function overloading.
