class employee {
        void work() {
                writeln("I am employee");
        }
}

class manager: employee {
        void work() {
                writeln("I am manager");
                }
}


void main() {
        employee e1 = new manager;//here
        e1.work();

        manager m3 = new manager;//--|here
