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> (map) (STL/CLR).

List greater than comparison.

Syntax

template<typename Key,  
    typename Mapped>  
    bool operator>(map<Key, Mapped>% left,  
        map<Key, Mapped>% right);

Parameters

left
Left container to compare.

right
Right container to compare.

Remarks

The operator function returns right < left. You use it to test whether left is ordered after right when the two maps are compared element by element.

Example

// cliext_map_operator_gt.cpp   
// compile with: /clr   
#include <cliext/map>   
  
typedef cliext::map<wchar_t, int> Mymap;   
int main()   
    {   
    Mymap c1;   
    c1.insert(Mymap::make_value(L'a', 1));   
    c1.insert(Mymap::make_value(L'b', 2));   
    c1.insert(Mymap::make_value(L'c', 3));   
  
// display contents " [a 1] [b 2] [c 3]"   
    for each (Mymap::value_type elem in c1)   
        System::Console::Write(" [{0} {1}]", elem->first, elem->second);   
    System::Console::WriteLine();   
  
// assign to a new container   
    Mymap c2;   
    c2.insert(Mymap::make_value(L'a', 1));   
    c2.insert(Mymap::make_value(L'b', 2));   
    c2.insert(Mymap::make_value(L'd', 4));   
  
// display contents " [a 1] [b 2] [d 4]"   
    for each (Mymap::value_type elem in c2)   
        System::Console::Write(" [{0} {1}]", elem->first, elem->second);   
    System::Console::WriteLine();   
  
    System::Console::WriteLine("[a b c] > [a b c] is {0}",   
        c1 > c1);   
    System::Console::WriteLine("[a b d] > [a b c] is {0}",   
        c2 > c1);   
    return (0);   
    }

 [a 1] [b 2] [c 3]  
 [a 1] [b 2] [d 4]  
[a b c] > [a b c] is False  
[a b d] > [a b c] is True
