operator< (stack) (STL/CLR)

Stack less than comparison.

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

Parameters

  • left
    Left container to compare.

  • right
    Right container to compare.

Remarks

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->stack::size (STL/CLR)() < right->size() You use it to test whether left is ordered before right when the two stacks are compared element by element.

Example

// cliext_stack_operator_lt.cpp 
// compile with: /clr 
#include <cliext/stack> 
 
typedef cliext::stack<wchar_t> Mystack; 
int main() 
    { 
    Mystack 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 
    Mystack 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 c] < [a b d] is {0}", 
        c1 < c2); 
    return (0); 
    } 
 
 a b c
 a b d
[a b c] < [a b c] is False
[a b c] < [a b d] is True
