How does memory management work with C++ vectors?

Can you explain how memory management works with C++ vectors?

Sure! C++ vectors manage memory automatically, but understanding how they allocate and deallocate memory is crucial.

What happens when a vector exceeds its capacity?

When a vector exceeds its capacity, it reallocates memory to a larger block, copies 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. Preallocating space can help.

How can I avoid memory leaks when using vectors?

To avoid memory leaks, ensure that you properly manage the lifetime of objects stored in vectors and let vectors handle their own memory.
