What are the advanced map features in C++11?

C++11 introduced several enhancements to the map container, including initializer lists, emplace, and more efficient memory management.

Can you explain how initializer lists work with maps?

Sure! Initializer lists allow you to initialize a map with a list of key-value pairs using curly braces, making the code cleaner.

What is the emplace function and how does it differ from insert?

The emplace function constructs elements in place, which can be more efficient than insert, as it avoids unnecessary copies.

Are there any performance improvements in C++11 maps?

Yes, C++11 maps have improved memory allocation strategies and better handling of move semantics, enhancing performance.
