How does memory management work in C++11 containers?

How does memory management work in C++11 containers?

In C++11, containers like vector, list, and map manage memory automatically. They allocate and deallocate memory as needed.

What happens when a container resizes?

When a container resizes, it allocates new memory for the larger size, copies existing elements to the new memory, and then deallocates the old memory.

Are there any performance implications of using these containers?

Yes, resizing can be costly in terms of performance, especially if it happens frequently. It's often better to reserve space in advance.

How can I avoid memory leaks with C++11 containers?

Using smart pointers like std::shared_ptr or std::unique_ptr can help manage memory automatically and prevent leaks.
