std::set<Key,Compare,Allocator>::rbegin, std::set<Key,Compare,Allocator>::

Returns a reverse iterator to the first element of the reversed set. It corresponds to the last element of the non-reversed set. If the set is empty, the returned iterator is equal to rend()

Parameters

(none)

Return value

Reverse iterator to the first element.

Complexity

Constant.

Notes

Because both iterator and const_iterator

The underlying iterator of the returned reverse iterator is the end iterator

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

Example

#include <iostream>
#include <set>
 
int main()
{
    std::set<unsigned> rep{1, 2, 3, 4, 1, 2, 3, 4};
 
    for (auto it = rep.crbegin(); it != rep.crend(); ++it)
    {
        for (auto n = *it; n > 0; --n)
            std::cout << "⏼" << ' ';
        std::cout << '\n';
    }
}
