public member function
<map>
const_reverse_iterator crend() const noexcept;
Return const_reverse_iterator to reverse end
Returns a const_reverse_iterator pointing to the theoretical element preceding the first element in the container (which is considered its reverse end).
Example
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

// multimap::crbegin/crend
#include <iostream>
#include <map>
int main ()
{
std::multimap<char,int> mymultimap = { {'x',100}, {'y',200}, {'x',300} };
// print content:
std::cout << "mymultimap backwards:";
for (auto rit = mymultimap.crbegin(); rit != mymultimap.crend(); ++rit)
std::cout << " [" << rit->first << ':' << rit->second << ']';
std::cout << '\n';
return 0;
}

Output:
mymultimap backwards: [y:200] [x:300] [x:100]

Iterator validity
No changes.
Data races
The container is accessed.
No contained elements are accessed by the call, but the iterator returned can be used to access them. 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.
