operator== (multimap) (STL/CLR)

Article
12/18/2017

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

List equal comparison.

Syntax

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

Parameters

left
Left container to compare.

right
Right container to compare.

Remarks

The operator function returns true only if the sequences controlled by left and right have the same length and, for each position i, left``[i] == right``[i]. You use it to test whether left is ordered the same as right when the two multimaps are compared element by element.

Example

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

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