Comparaison "non égal" de listes

template<typename Key,
    typename Mapped>
    bool operator!=(map<Key, Mapped>% left,
        map<Key, Mapped>% right);

Paramètres

left
Conteneur gauche à comparer.
right
Conteneur droit à comparer.

Notes

La fonction d'opérateur retourne !(left == right). Vous l'utilisez pour tester si left n'est pas ordonné comme right lorsque les deux multimaps sont comparées élément par élément.

Exemple

// cliext_map_operator_ne.cpp 
// compile with: /clr 
#include <cliext/map> 
 
typedef cliext::map<wchar_t, int> Mymap; 
int main() 
    { 
    Mymap c1; 
    c1.insert(Mymap::make_value(L'a', 1)); 
    c1.insert(Mymap::make_value(L'b', 2)); 
    c1.insert(Mymap::make_value(L'c', 3)); 
 
// display contents " [a 1] [b 2] [c 3]" 
    for each (Mymap::value_type elem in c1) 
        System::Console::Write(" [{0} {1}]", elem->first, elem->second); 
    System::Console::WriteLine(); 
 
// assign to a new container 
    Mymap c2; 
    c2.insert(Mymap::make_value(L'a', 1)); 
    c2.insert(Mymap::make_value(L'b', 2)); 
    c2.insert(Mymap::make_value(L'd', 4)); 
 
// display contents " [a 1] [b 2] [d 4]" 
    for each (Mymap::value_type elem in c2) 
        System::Console::Write(" [{0} {1}]", elem->first, elem->second); 
    System::Console::WriteLine(); 
 
    System::Console::WriteLine("[a b c] != [a b c] is {0}", 
        c1 != c1); 
    System::Console::WriteLine("[a b c] != [a b d] is {0}", 
        c1 != c2); 
    return (0); 
    }
