deque : : difference_type (STL/CLR)

Les types d'une distance signée entre deux éléments.

    typedef int difference_type;

Notes

Le type décrit un compte d'éléments signés.

Exemple

// cliext_deque_difference_type.cpp 
// compile with: /clr 
#include <cliext/deque> 
 
int main() 
    { 
    cliext::deque<wchar_t> c1; 
    c1.push_back(L'a'); 
    c1.push_back(L'b'); 
    c1.push_back(L'c'); 
 
// display initial contents " a b c" 
    for each (wchar_t elem in c1) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
 
// compute positive difference 
    cliext::deque<wchar_t>::difference_type diff = 0; 
    for (cliext::deque<wchar_t>::iterator it = c1.begin(); 
        it != c1.end(); ++it) ++diff; 
    System::Console::WriteLine("end()-begin() = {0}", diff); 
 
// compute negative difference 
    diff = 0; 
    for (cliext::deque<wchar_t>::iterator it = c1.end(); 
        it != c1.begin(); --it) --diff; 
    System::Console::WriteLine("begin()-end() = {0}", diff); 
    return (0); 
    }
