operator< (list) (STL/CLR)

 

For the latest documentation on Visual Studio 2017 RC, see Visual Studio 2017 RC Documentation.

List less than comparison.

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

Parameters

left
Left container to compare.

right
Right container to compare.

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]. Otherwise, it returns left``->size() < right``->size() You use it to test whether left is ordered before right when the two lists are compared element by element.
