C++11 Allocator vs New: What's the Difference?

What is the difference between the C++11 allocator and the new operator?

The C++11 allocator is a way to manage memory allocation for containers, while 'new' is a general-purpose memory allocation operator.

Can you explain how allocators improve memory management?

Allocators allow for custom memory management strategies, which can optimize performance and reduce fragmentation in containers.

When should I use an allocator instead of new?

Use an allocator when you need fine control over memory allocation, especially in performance-critical applications or custom containers.

Are there any downsides to using allocators?

Yes, using allocators can add complexity to your code and may not always yield performance benefits for simpler applications.
