Question

Using C++, you must create two Traffic Signal objects from the class you just created (screen shot below) to prove that your class works properly for GDOT, the first object should use the default constructor and the second object should use the overloaded constructor.
Using the objects you just created in 1), call the method (in C++) to change the light to the next in the sequence.
