How does memory management work in C++ standard containers?

Can you explain how memory management works in C++ standard containers?

Sure! C++ standard containers like vector, list, and map manage memory automatically, but understanding their behavior is key.

What happens when a vector resizes?

When a vector resizes, it allocates a new larger memory block, copies existing elements to it, and frees the old block.

Are there any performance implications with this resizing?

Yes, frequent resizing can lead to performance overhead. It's often better to reserve space in advance if you know the size.

How do smart pointers fit into this memory management?

Smart pointers like std::unique_ptr and std::shared_ptr help manage dynamic memory, ensuring proper deallocation.
