Overview Shared vs Unique vs Weak Pointers

1. What happens when multiple `std::shared_ptr` instances share ownership of the same object, and all of them go out of scope?

2. Which of the following is true about `std::unique_ptr`?

3. Why would you use a `std::weak_ptr` instead of a `std::shared_ptr`?

What happens when multiple std::shared_ptr instances share ownership of the same object, and all of them go out of scope?

Select the correct answer

The object remains alive indefinitely.

The object can never be deleted manually.

The object is destroyed immediately when the first shared_ptr is destroyed.

The object is destroyed when the last shared_ptr managing it goes out of scope.

Which of the following is true about std::unique_ptr?

Select the correct answer

It can be copied freely.

It ensures exclusive ownership of an object.

It allows multiple pointers to manage the same object.

It has a reference counter like std::shared_ptr.

Why would you use a std::weak_ptr instead of a std::shared_ptr?

Select the correct answer

To delete objects manually.

To speed up access to an object.

To break circular references and avoid memory leaks.

To increase reference count without owning the object.

Oliko kaikki selvää?

Miten voimme parantaa sitä?
