指定已還原的受控制序列結尾。

    reverse_iterator rend();

備註

成員函式會傳回反向的 iterator 那些只是超出開頭受控制序列的點。因此，它會指定反向序列的 end。您要用它來取得的 Iterator 可指定以相反順序顯示的受控制序列之 current 結尾，但是，如果受控制序列的長度變更，它的狀態也可以變更。

範例

// cliext_deque_rend.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(); 
 
// inspect first two items 
    cliext::deque<wchar_t>::reverse_iterator rit = c1.rend(); 
    --rit; 
    System::Console::WriteLine("*-- --rend() = {0}", *--rit); 
    System::Console::WriteLine("*--rend() = {0}", *++rit); 
 
// alter first two items and reinspect 
    *--rit = L'x'; 
    *++rit = L'y'; 
    for each (wchar_t elem in c1) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
    return (0); 
    }
