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.

### [edit] Parameters

(none)

### [edit] Return value

reverse iterator to the first character

### [edit] Exceptions

(none) | (until C++11)

### [edit] Complexity

Constant

### [edit] Example

Run this code

    #include <iostream>

    #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:
