Returns a const iterator to the first element in a reversed deque.
const_reverse_iterator crbegin( ) const;
Return Value
A const reverse random-access iterator addressing the first element in a reversed deque Class or addressing what had been the last element in the unreversed deque.

With the return value of crbegin, the deque object cannot be modified.
Example
// deque_crbegin.cpp
// compile with: /EHsc
#include <deque>
#include <iostream>
int main( )
{
using namespace std;
deque <int> v1;
deque <int>::iterator v1_Iter;
deque <int>::const_reverse_iterator v1_rIter;
v1.push_back( 1 );
v1.push_back( 2 );
v1_Iter = v1.begin( );
cout << "The first element of deque is "
<< *v1_Iter << "." << endl;
v1_rIter = v1.crbegin( );
cout << "The first element of the reversed deque is "
<< *v1_rIter << "." << endl;
}
The first element of deque is 1. The first element of the reversed deque is 2.
