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

Queue equal comparison.

Syntax

template<typename Value,  
    typename Container>  
    bool operator==(queue<Value, Container>% left,  
        queue<Value, Container>% 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 queues are compared element by element.

Example

// cliext_queue_operator_eq.cpp   
// compile with: /clr   
#include <cliext/queue>   
  
typedef cliext::queue<wchar_t> Myqueue;   
int main()   
    {   
    Myqueue 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   
    Myqueue 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 True  
[a b c] == [a b d] is False
