+
+The C++ STL map class **.empty()** function is a member function of the STL map class. This function can be called on an STL map object, and returns true if the map object on which it is called is empty (e.g. contains no key-value pairs), and returns false if the map object contains one or more elements. 
+
+## Syntax
+
+The map class .empty() member function can be called using the dot (.) operator, as shown below. The function takes no parameters, and the return value is either a boolean true value or a boolean false value, depending on whether the map object on which the function is called is or is not empty, respectively.
