I’m unsure if I have completed the first 12 steps correctly. Was hoping someone can skim over my code and tell me if I completed all steps correctly. One thing that concerns me is what the console looks like in the screenshot versus what step 13 shows.

//Make sure that both classes are printable, call Display() on tdl and pm.
//tdl.Display();

//Call Reset() and Display() with tdl and pm. In other words, both objects should display, then reset, then display again.
