What are the new features in C++11 related to maps?

C++11 introduced several enhancements for maps, including initializer lists, range-based for loops, and improved performance.

Can you explain how initializer lists work with maps?

Sure! Initializer lists allow you to create a map and populate it in a single statement, like this: std::map<int, std::string> myMap = {{1, "one"}, {2, "two"}};.

What about the performance improvements?

C++11 improved the performance of maps by optimizing memory allocation and providing better algorithms for searching and inserting elements.

Are there any new functions added to the map class?

Yes, C++11 added functions like emplace() which allows you to construct elements in place, improving efficiency.
