Webemplace () is a built-in function in C++ STL which inserts the key and its element in the map container. It effectively increases the container size by one. If the same key is emplaced more than once, the map stores the first element only as the map is a container which does not store multiple keys of the same value. Example of emplace () : WebC++ Utilities library std::pair std::pair is a class template that provides a way to store two heterogeneous objects as a single unit. A pair is a specific case of a std::tuple with two elements. If neither T1 nor T2 is a possibly cv-qualified class type with non-trivial destructor, or array thereof, the destructor of pair is trivial.
