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

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

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

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

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

Is it efficient to use std::vector for large datasets?

Yes, std::vector is efficient for large datasets, but consider reserving space in advance to minimize reallocations.

Can I control the memory allocation strategy of std::vector?

You can't directly control the allocation strategy, but you can use methods like reserve() to optimize memory usage.
