Question

The weak_ptr can share ownership of a piece of dynamically allocated memory.

Options:
A) True
B) False

Answer 1

The weak_ptr in C++ can share ownership of a piece of dynamically allocated memory. However, unlike shared_ptr, it does not participate in reference counting and does not control the object's lifetime.

Step-by-step explanation:

True .The weak_ptr in C++ can share ownership of a piece of dynamically allocated memory.

However, unlike shared_ptr, weak_ptr does not participate in reference counting and does not control the lifetime of the object it points to.

Instead, it is used to observe an object managed by shared_ptr but without keeping it alive. This is useful in scenarios where we want to avoid circular dependencies between objects.
