Comment out the entire implementation of Pet::eat, all the way from the void Pet::eat(int amt) to its close curly brace. Why do you get the resulting build error?

In main, replace myPets[0] = new Pet("Fluffy", 2); with myPets[0] = new Pet("Fluffy"); or myPets[0] = new Pet;, Why do you get the resulting compilation errors?

Try removing the const from the implementation, but not the declaration of the alive member function. What happens? Why?

Try removing the const from both the declaration and the implementation of the alive member function. Explain why the use of that function doesn't compile in reportStatus, but does compile in careFor and main.
