Create a class called Employee that includes four pieces of information as data members — a first name (type string), a middle name (type string) , a last name (type string)and a monthly salary (type int). Your class should have a constructor that initializes the four data members. Provide a set and a get function for each data member. If the monthly salary is not positive, set it to 0. Write a c++ test program that demonstrates class Employee’s capabilities. Create two Employee objects and display each object’s yearly salary.
