Learn about Maps in STL in C++ language and its member functions in details in this tutorial. or not, if it is present the entry is not inserted in the map and the iterator to the existing key is returned otherwise new entry is inserted in the map. Learn to use the Standard Template Library map class as an associative array and access data stored in a map with iterators. require two, and possibly three, types for the template: std::map 14 Nov 2018 iterator find( const Key& key );. (1). const_iterator find( const Key& key ) const;. (2). template< class K > iterator find( const K& x );. (3), (since If you really need to hide the value that the "real" iterator returns (for example [Tip: when looking at Boost documentation for a new class, read the "examples" at the end first. for(std::map::iterator iter = myMap.begin(); iter !=11 Sep 2011 Lets take a look at some examples of using iterators.
