Returns an iterator referring to the past-the-end element in the map container.
The past-the-end element is the theoretical element that would follow the last element in the map container. It does not point to any element, and thus shall not be dereferenced.
Because the ranges used by functions of the standard library do not include the element pointed by their closing iterator, this function is often used in combination with map::begin to specify a range including all the elements in the container.
If the container is empty, this function returns the same as map::begin.
If the map object is const-qualified, the function returns a const_iterator. Otherwise, it returns an iterator.
Member types iterator and const_iterator are bidirectional iterator types pointing to elements.
Output:
No contained elements are accessed by the call, but the iterator returned can be used to access or modify elements. Concurrently accessing or modifying different elements is safe.
The copy construction or assignment of the returned iterator is also guaranteed to never throw.

Return iterator to end
The past-the-end element is the theoretical element that would follow the last element in the map container. It does not point to any element, and thus shall not be dereferenced.
Because the ranges used by functions of the standard library do not include the element pointed by their closing iterator, this function is often used in combination with map::begin to specify a range including all the elements in the container.
If the container is empty, this function returns the same as map::begin.
Parameters
noneReturn Value
An iterator to the past-the-end element in the container.If the map object is const-qualified, the function returns a const_iterator. Otherwise, it returns an iterator.
Member types iterator and const_iterator are bidirectional iterator types pointing to elements.

Output:

Complexity
Constant.Iterator validity
No changes.Data races
The container is accessed (neither the const nor the non-const versions modify the container).No contained elements are accessed by the call, but the iterator returned can be used to access or modify elements. Concurrently accessing or modifying different elements is safe.
Exception safety
No-throw guarantee: this member function never throws exceptions.The copy construction or assignment of the returned iterator is also guaranteed to never throw.
