How does memory management work in C++ STL?

Can you explain how memory management works in C++ STL?

Sure! C++ Standard Template Library (STL) manages memory through dynamic allocation and deallocation using containers.

What are the main containers in STL that handle memory?

The main containers include vectors, lists, and maps. Each has its own memory management strategies.

How does a vector manage its memory?

A vector manages memory by allocating a contiguous block of memory and resizing it as needed, using copy or move semantics.

What happens when a vector exceeds its capacity?

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

Are there any best practices for memory management in STL?

Yes, use smart pointers, avoid unnecessary copies, and prefer reserve() for vectors to minimize reallocations.
