What are some common allocator patterns in C++?

Common allocator patterns in C++ include the default allocator, pool allocator, and custom allocators. Would you like to know more about any specific one?

Can you explain the pool allocator?

A pool allocator manages a fixed-size block of memory, allowing for efficient allocation and deallocation of objects of the same size. This reduces fragmentation and improves performance.

What are the advantages of using a custom allocator?

Custom allocators can optimize memory usage for specific data structures, improve performance, and reduce memory fragmentation. They allow developers to tailor memory management to their application's needs.

How do I implement a simple custom allocator?

To implement a simple custom allocator, you need to define allocation and deallocation functions, manage memory blocks, and ensure proper alignment. Would you like a code example?
