operator<= (queue) (STL/CLR)

2013-06-07

排队小于或等于比较。

template<typename Value,
    typename Container>
    bool operator<=(queue<Value, Container>% left,
        queue<Value, Container>% right);

参数

left
比较左侧的容器。
right
比较的正确的容器。

备注

运算符函数返回 !(right<left)。使用该测试 left 如果没有在 right 后进行排序，当两个队列是比较组件的元素。

示例

// cliext_queue_operator_le.cpp 
// compile with: /clr 
#include <cliext/queue> 
 
typedef cliext::queue<wchar_t> Myqueue; 
int main() 
    { 
    Myqueue c1; 
    c1.push(L'a'); 
    c1.push(L'b'); 
    c1.push(L'c'); 
 
// display contents " a b c" 
    for each (wchar_t elem in c1.get_container()) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
 
// assign to a new container 
    Myqueue c2; 
    c2.push(L'a'); 
    c2.push(L'b'); 
    c2.push(L'd'); 
 
// display contents " a b d" 
    for each (wchar_t elem in c2.get_container()) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
 
    System::Console::WriteLine("[a b c] <= [a b c] is {0}", 
        c1 <= c1); 
    System::Console::WriteLine("[a b d] <= [a b c] is {0}", 
        c2 <= c1); 
    return (0); 
    }
