How does memory management work with std::vector in C++11?

How does memory management work with std::vector in C++11?

In C++11, std::vector manages memory automatically. It allocates memory dynamically and resizes as needed.

What happens when I add more elements than the current capacity?

When you exceed the current capacity, std::vector allocates a new larger memory block, copies existing elements, and deallocates the old block.

Can I control the capacity of a std::vector?

Yes, you can use the reserve() method to pre-allocate memory and control the capacity of a std::vector.

What about memory leaks with std::vector?

std::vector automatically manages memory, so it helps prevent memory leaks. However, if you store pointers, you need to manage those manually.
