C++ Map Brackets at Marlene Chandler blog

C++ Map Brackets. Unlike other data structures in c++, the map stores its elements in a sorted order, making retrieval and manipulation of data. To create a map, use the map keyword, and specify the type of both the key and the value it should store within angle brackets <>. The argument(s) for the key that you pass to emplace() are directly forwarded to a foo constructor call within. Operator [] returns a reference to the value that is mapped. Template t& at(const k& x ); (3) (since c++26) templateconst t& at(const k& x )const; Search, removal, and insertion operations have logarithmic complexity. If you access a key using the indexing operator [] that is not currently a part of a map, then it automatically adds a key for you.
