1. Create a class called Faculty that includes three pieces of information as data members:
a. a first name (type string)
b. a last name (type string)
c. a monthly salary (type int).
They should be private.
2. This class should have a constructor that initializes the three data members.
3. Provide a public set function and a public get function for each data member. If the monthly salary is not positive, set it to 0.
4. In the main function, create two Faculty objects and display each object’s yearly salary.
5. Then give each Faculty a 10 percent raise and display each Faculty’s yearly salary again.
