operator< (vector) (STL/CLR)

Vector 小于比较

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

参数

left
比较左边的容器。
right
比较右边的容器。

备注

如果运算符函数返回 TRUE，最低位置的i，其中，!(right[i] < left[i]) 是正确的，left[i] < right[i]。否则，返回left->size() < right->size() 您使用它测试 left 在 right 之前是否有序，当2个 vector 按元素比较时。

示例

// cliext_vector_operator_lt.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 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::vector<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); 
    }
