What is the memory management of vectors in C++?

Can you explain how memory is managed for vectors in C++?

In C++, vectors manage memory dynamically. They allocate memory on the heap and can resize automatically.

What happens when a vector exceeds its capacity?

When a vector exceeds its capacity, it allocates a new larger memory block, copies the existing elements, and frees the old memory.

Is it efficient to use vectors for large datasets?

Vectors are generally efficient for large datasets, but frequent resizing can lead to performance overhead.

How can I reserve memory for a vector in advance?

You can use the reserve() method to allocate memory for a specific number of elements in advance.
