Pretty easy, for some type T:

Code:

std::queue<T> queue1;
// ...
std::queue<T> queue2(queue1); // copy construction
std::queue<T> queue3;
queue3 = queue1; // copy assignment

Use a constructor:

Code:

std::queue<my_type> queue (other_queue);

(Too late)

so to copy a queue i should use a
1)default constructor
2)copy constructor

then to use the = operatoer
queue3 = queue1;

as simple as that?

More like: prefer to use the copy constructor. But if you already have a queue, use the copy assignment operator.
