The new home for Visual Studio documentation is Visual Studio 2017 Documentation on docs.microsoft.com.

The latest version of this topic can be found at operator<= (pair) (STL/CLR).

Pair less than or equal comparison.

Syntax

template<typename Value1,  
    typename Value2>  
    bool operator<=(pair<Value1, Value2>% left,  
        pair<Value1, Value2>% right);

Parameters

left
Left pair to compare.

right
Right pair to compare.

Remarks

The operator function returns !(``right < left``). You use it to test whether left is not ordered after right when the two pairs are compared element by element.

Example

// cliext_pair_operator_le.cpp   
// compile with: /clr   
#include <cliext/utility>   
  
int main()   
    {   
    cliext::pair<wchar_t, int> c1(L'x', 3);   
    System::Console::WriteLine("[{0}, {1}]", c1.first, c1.second);   
    cliext::pair<wchar_t, int> c2(L'x', 4);   
    System::Console::WriteLine("[{0}, {1}]", c2.first, c2.second);   
  
    System::Console::WriteLine("[x 3] <= [x 3] is {0}",   
        c1 <= c1);   
    System::Console::WriteLine("[x 4] <= [x 3] is {0}",   
        c2 <= c1);   
    return (0);   
    }

[x, 3]  
[x, 4]  
[x 3] <= [x 3] is True  
[x 4] <= [x 3] is False
