What are some advanced topics in C++ STL?

Some advanced topics in C++ STL include custom allocators, advanced iterators, and the use of function objects.

Can you explain what custom allocators are?

Custom allocators allow you to define how memory is allocated and deallocated for STL containers, optimizing performance.

What are function objects and how are they used in STL?

Function objects, or functors, are objects that can be called as if they were functions. They are often used with algorithms.

How do I create a custom iterator?

To create a custom iterator, you need to define a class that implements the required iterator traits and overloads the necessary operators.
