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

Question: 1 / 565

What is the behavior of a const reference in C++ when binding to a temporary object?

It extends the lifetime of the temporary object to the lifetime of the reference

A const reference in C++ extends the lifetime of the temporary object it is bound to, ensuring that the object remains valid for the duration of the reference. The other options are incorrect because creating a copy on the stack would not maintain the original object, immediately destroying the temporary is not the behavior of a reference, and converting the temporary into a dynamic object would not extend its lifetime to the reference.
