operator< (list) (STL/CLR)

發行項

清單小於比較。

template<typename Value>
    bool operator<(list<Value>% left,
        list<Value>% right);

參數

left
若要比較的左的容器。
right
若要比較的正確容器。

備註

The operator function returns true if, for the lowest position i for which !(right[i] < left[i]) it is also true that left[i] < right[i]. 否則，它會傳回left->size() < right->size()您用它來測試是否left之前排序right當兩份清單是由項目比較的項目。

範例

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