What are some advanced techniques in C++ STL?
Some advanced techniques include using custom allocators, implementing policy-based data structures, and leveraging move semantics.
Can you explain how to use custom allocators?
Custom allocators allow you to control memory allocation for STL containers. You can define your own allocator class and pass it to the container.
What are policy-based data structures?
Policy-based data structures are templates that allow you to customize the behavior of STL containers by passing policies as template parameters.
How does move semantics improve performance?
Move semantics reduce unnecessary copying of objects, allowing resources to be transferred instead, which enhances performance.
Can you give an example of a policy-based data structure?
Sure! An example is a priority queue that uses a custom comparator to define the ordering of elements.
