The unordered_multiset::get_allocator() function is a STL function in C++ which is used to include unorder_multiset header file in program. This function gets the stored allocator object and returns the allocator object which is used to construct the container. It is a public member function.
allocator_type get_allocator() const;
Here allocator_type is the type of the allocator which is used by the container.
Parameters: It does not accepts any parameter.
Return Value: It returns the allocator type.
Below program illustrate get_allocator method in C++ STL:
allocator is : true
Complexity: It takes constant time of complexity to perform operation.
