      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.

      Notes

      libc++ backportscrend() to C++98 mode.

      [edit]Example

      Run this code
      #include <algorithm>#include <iostream>#include <numeric>#include <string>#include <list> int main(){std::list<int> nums{1,2,4,8,16};std::list<std::string> fruits{"orange","apple","raspberry"};std::list<char> empty; // Print list.std::for_each(nums.rbegin(), nums.rend(),[](constint n){std::cout<< n<<' ';});std::cout<<'\n'; // Sums all integers in the list nums (if any), printing only the result.std::cout<<"Sum of nums: "<<std::accumulate(nums.rbegin(), nums.rend(),0)<<'\n'; // Prints the first fruit in the list fruits, checking if there is any.if(!fruits.empty())std::cout<<"First fruit: "<<*fruits.rbegin()<<'\n'; if(empty.rbegin()== empty.rend())std::cout<<"list 'empty' is indeed empty.\n";}

      Output:

      16 8 4 2 1Sum of nums: 31First fruit: raspberrylist 'empty' is indeed empty.
