What are the advanced features of maps in C++11?

C++11 introduced several advanced features for maps, including initializer lists, emplace, and improved performance.

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.

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 compared to previous versions?

Yes, C++11 maps have improved performance due to better memory management and optimizations in the underlying data structures.
