reverse_iterator rbegin();
const_reverse_iterator rbegin() const;
const_reverse_iterator crbegin() const;		(since C++11)

Returns a reverse iterator to the first character of the reversed string. It corresponds to the last character of the non-reversed string.

Constant.

Example

#include <iostream>
#include <algorithm>
#include <iterator>
#include <string>
 
int main()
{
    std::string s("Exemplar!");
    *s.rbegin() = 'y';
    std::cout << s << '\n'; // "Exemplary"
 
    std::string c;
    std::copy(s.crbegin(), s.crend(), std::back_inserter(c));
    std::cout << c << '\n'; // "yralpmexE"
}

Output:
