C++ map end() FunctionC++ map end() function is used to return an iterator which is next to the last entry in the map. SyntaxParameterNone Return valueIt returns an iterator pointing next to the last element of the map. Example 1Let's see a simple example for end() function. Output: a => C++ b => Java c => SQL In the above, end() function is used to return an iterator pointing next to the last element in the mymap map. Example 2Let's see a simple example to iterate over the map using for-each loop. Output: Room1 = 100 Room2 = 200 Room3 = 300 In the above example, we are using an STL algorithm std::for-each to iterate over the map. It will iterate on each of the map element and call the callback provided by us. Example 3Let's see a simple example to iterate over the map using while loop. Output: 100 = Nikita 200 = Deep 300 = Priya 400 = Suman 500 = Aman In the above example, end() function is used to return an iterator pointing next to the last element in the mymap map. Example 4Let's see a simple example. Output: Elements are: 10 * 10 = 100 20 * 20 = 400 30 * 30 = 900 In the above example, end() function is used to return an iterator pointing next to the last element in the mymap map.
