Chapter 9 defined the struct studentType to implement the basic properties of a student. Define the class studentType with the same components as the struct studentType, and add member functions to manipulate the data members. (Note that the data members of the class studentType must be private.) Write a program to illustrate how to use the class studentType. Struct studentType: struct studentType { string firstName; string lastName; char courseGrade; int testScore; int programmingScore; double GPA; };
