How does C++ manage memory for vectors?

C++ uses dynamic memory allocation for vectors. When you create a vector, it allocates memory on the heap.

What happens when a vector grows beyond its capacity?

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

Can I control the capacity of a vector?

Yes, you can use the reserve() method to pre-allocate memory for a specific number of elements.

What is the difference between size() and capacity()?

size() returns the number of elements in the vector, while capacity() returns the total number of elements the vector can hold without reallocating.
