operator== (multiset) (STL/CLR)

Article

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

List equal comparison.

Syntax

template<typename Key>  
    bool operator==(multiset<Key>% left,  
        multiset<Key>% 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 multisets are compared element by element.

Example

// cliext_multiset_operator_eq.cpp   
// compile with: /clr   
#include <cliext/set>   
  
typedef cliext::multiset<wchar_t> Mymultiset;   
int main()   
    {   
    Mymultiset c1;   
    c1.insert(L'a');   
    c1.insert(L'b');   
    c1.insert(L'c');   
  
// display contents " a b c"   
    for each (wchar_t elem in c1)   
        System::Console::Write(" {0}", elem);   
    System::Console::WriteLine();   
  
// assign to a new container   
    Mymultiset c2;   
    c2.insert(L'a');   
    c2.insert(L'b');   
    c2.insert(L'd');   
  
// display contents " a b d"   
    for each (wchar_t elem in c2)   
        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 True  
[a b c] == [a b d] is False
