public member function
<vector>
const_reverse_iterator crend() const noexcept;
Return const_reverse_iterator to reverse end
Returns a const_reverse_iterator pointing to the element right before the first element in the container (which is considered its reverse end).
Return Value
A const_reverse_iterator to the reverse beginning of the sequence.
Member type const_reverse_iterator is a reverse random access iterator type.
Example
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

// vector::crbegin/crend
#include <iostream>
#include <vector>
int main ()
{
std::vector<int> myvector = {1,2,3,4,5};
std::cout << "myvector backwards:";
for (auto rit = myvector.crbegin(); rit != myvector.crend(); ++rit)
std::cout << ' ' << *rit;
std::cout << '\n';
return 0;
}
|
Output:
myvector backwards: 5 4 3 2 1

Iterator validity
No changes.
Data races
The container is accessed.
No contained elements are accessed by the call. Concurrently accessing or modifying them is safe.
