vector::rend (STL/CLR)

项目

指定反转的受控序列的末尾。

    reverse_iterator rend();

备注

该成员函数返回一个反向迭代器，指向刚刚超越控制序列的开头。因此，它指定反向序列的 end。用于获取一个迭代器，该迭代器指定相反顺序的受控序列的 current 末尾，但如果受控序列的长度发生更改，则该迭代器的状态也会发生更改。

示例

// cliext_vector_rend.cpp 
// compile with: /clr 
#include <cliext/vector> 
 
int main() 
    { 
    cliext::vector<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::vector<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); 
    }
