how to print out all elements in a std::stack or std::queue conveniently

Question

If I do not to want to create a new container in order to do so?

Answer 1

ostream & operator<<(ostream & os, stack my_stack) //function header
{
    while(!my_stack.empty()) //body
    {
        os << my_stack.top() << " ";
        my_stack.pop();
    }
    return os; // end of function
}


/*
using this simple overloaded operator function, you're able to print out all the components of a stack by doing a simple cout << your_stack_name;*/
