#includeIn this example, we create a map of integer keys and string values. We insert three elements into the map using the insert function with pairs. We then print the size of the map and delete the element with key 2 using the erase function. Finally, we iterate over the map and print the remaining elements. The C++ map is part of the template library and is included in the standard C++ library, so it does not require any external package or library.#include
