std::basic_string<CharT,Traits,Allocator>::rbegin, std::basic_string<CharT,Traits,Allocator>::crbegin

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.

# Declarations

reverse_iterator rbegin();

(noexcept since C++11) (constexpr since C++20)

const_reverse_iterator rbegin() const;

(noexcept since C++11) (constexpr since C++20)

const_reverse_iterator crbegin() const noexcept;

(since C++11) (constexpr since C++20)

# Return value

Reverse iterator to the first character.

# Notes

libc++ backports crbegin() to C++98 mode.

# Example

#include <algorithm>
#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"
}
