Returns a reverse iterator past the last element of the reversed*this. It corresponds to the element preceding the first element of the non-reversed*this.
This returned iterator only acts as a sentinel. It is not guaranteed to bedereferenceable.

[edit]Return value
Reverse iterator to the element following the last element.
[edit]Complexity
Constant.
[edit]Example
Run this code
#include <algorithm>#include <iostream>#include <array> int main(){std::array<int,11> a{1,11,11,35,0,12,79,76,76,69,40}; // Print elements of container in reverse order using const_reverse_iterator's.std::for_each(a.crbegin(), a.crend(),[](int e){std::cout<< e<<' ';});std::cout<<'\n'; // Modify each element of container using non-const reverse_iterator's.std::for_each(a.rbegin(), a.rend(),[](int& e){ e+=32;}); // Print elements as chars in reverse order using const_reverse_iterator's.std::for_each(a.crbegin(), a.crend(),[](char e){std::cout<< e;});std::cout<<'\n';}
Output:
