Answer #1

Private: if you declare any variable/method as Private than you can't access the variable/method outside of that class. So strictly variable/method is available only with in the class.

Protected: if you declare any variable/method as Protected than we can access variable/method with in the class as well and in all its child classes

So if you want variable/method should available with in the class than you should use Private. if you want share the variable/method to its child classes than you should use Protected

There is no risk as it is available only for its child classes

Suppose that a test for determining whether a person has been infected with COVID-19 has a 20% rate of false positives (i.e. in 20% of applications, the test falsely indicates that a person has been infected with COVID-19 when they actually have not). Now, consider the likelihood that when 100 healthy people are tested, the test falsely indicates that between 10 and 30 of them are infected. c. Before you use the normal approximation to calculate P(10 ≤ x≤ 30),...

**[70 pts]** You will be writing a (rather primitive) online store simulator. It will have these classes: Product, Customer, and Store. All data members of each class should be marked as **private** (a leading underscore in the name). Since they're private, if you need to access them from outside the class, you should do so via get or set methods. Any get or set methods should be named per the usual convention ("get_" or "set_" followed by the name of...
