Explanation / Answer

1) Private keyword or function cannot be accessed, or even viewed from outside the class. Only the class and friend functions can access private members.

2) getR is the extractor or accessor member function that can be used to return the value of a data attribute within the class.

A naming convention must exist, and the name of the accessor must begin with the "Get" prefix.

3)setI is the mutator member function that can be used to modify the value of a data attribute within the class.

A naming convention must exist, with the name of the accessor beginning with the "Set" prefix
