Los tipos de una distancia firmados entre dos elementos.

    typedef int difference_type;

Comentarios

El tipo describe un recuento de elementos posiblemente negativo.

Ejemplo

// cliext_priority_queue_difference_type.cpp 
// compile with: /clr 
#include <cliext/queue> 
 
typedef cliext::priority_queue<wchar_t> Mypriority_queue; 
int main() 
    { 
    Mypriority_queue c1; 
    c1.push(L'a'); 
    c1.push(L'b'); 
    c1.push(L'c'); 
 
// display initial contents " a b c" 
    for each (wchar_t elem in c1.get_container()) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
 
// compute negative difference 
    Mypriority_queue::difference_type diff = c1.size(); 
    c1.push(L'd'); 
    c1.push(L'e'); 
    diff -= c1.size(); 
    System::Console::WriteLine("pushing 2 = {0}", diff); 
 
// compute positive difference 
    diff = c1.size(); 
    c1.pop(); 
    c1.pop(); 
    c1.pop(); 
    diff -= c1.size(); 
    System::Console::WriteLine("popping 3 = {0}", diff); 
    return (0); 
    }
