    int main(){
        std::stack<int> mystack;

        mystack.push(0);    //pushing elements using push()
        mystack.push(1);
        mystack.push(2);

        while (!mystack.empty()) {
            std::cout << ' ' << mystack.top();
            mystack.pop();  //deleting elements using pop()
        }

        return 0;
    }
