Model III. (20 min) Designing a C++ Class start time: A simple class might have only one data field and a few methods that manipulate that data field. Data fields will be represented in the C++ class by a member/instance variable. By marking this instance variable private, we will have the opportunity to handle invalid values. By labeling this instance variable private, we will have the opportunity to handle invalid values. Create and save a new C++ class (Salary.cpp) with the following code: /** * Represents the salary for a person class Salary private: double annual; public: void setAnnualSalary(double salary) { annual = salary: 3 double getAnnualSalary() { return annual; } }; Instructions: Now add the following main method to the end of the Salary class file (outside of the class): int main() { Salary pay; pay.setAnnualSalary (64100); return 0; 3 Critical Thinking Questions 21.
