unordered_multimap::cend

Article

Désigne la fin de la séquence contrôlée.

const_iterator cend() const;

Notes

La fonction membre retourne un itérateur vers l'avant const qui pointe juste au delà de la fin de la séquence.

Exemple

// std_tr1__unordered_map__unordered_multimap_cend.cpp 
// compile with: /EHsc 
#include <unordered_map> 
#include <iostream> 
 
typedef std::unordered_multimap<char, int> Mymap; 
int main() 
    { 
    Mymap c1; 
 
    c1.insert(Mymap::value_type('a', 1)); 
    c1.insert(Mymap::value_type('b', 2)); 
    c1.insert(Mymap::value_type('c', 3)); 
 
// display contents " [c 3] [b 2] [a 1]" 
    for (Mymap::const_iterator it = c1.cbegin(); 
        it != c1.cend(); ++it) 
        std::cout << " [" << it->first << ", " << it->second << "]"; 
    std::cout << std::endl; 
 
// inspect last two items " [a 1] [b 2]" 
    Mymap::const_iterator it2 = c1.cend(); 
    --it2; 
    std::cout << " [" << it2->first << ", " << it2->second << "]"; 
    --it2; 
    std::cout << " [" << it2->first << ", " << it2->second << "]"; 
    std::cout << std::endl; 
    return (0); 
    }
