Create an Employee class that includes three private data members

Create an Employee class that includes three private data members— firstName (type string), lastName (type string), and monthlySalary (type int ). It also includes several public member functions. 1. A constructor initializes the three data members. 2. A setFirstName function accepts a string parameter and does not return any data. It sets the firstName. 3. A getFirstName function does not accept any parameter and returns a string. It returns the firstName. 4. A setLastName function accepts a string parameter and does not return any data. It sets the lastName. 5. A getLastName function does not accept any parameter and returns a string. It returns the lastName. 6. A setMonthlySalary function accepts an integer parameter and does not return any data. It sets the monthlySalary. If the monthly salary is less than or equal zero, set it to 1000 and it displays the employee’s first name, last name and the inputted salary with a statement “**==The salary is set to $1000.” 7. A getMonthlySalary function does not accept any parameter and returns an integer. It returns the monthlySalary. 8. An increaseMonthlySalary function accepts an integer parameter and does not return any data. It increases the monthlySalary by integer%. The increase could be positive or negative. When this function is called the salary adjusted employee’s name and salary information will be displayed (please see the following image for details). This assignment comes with a CISP400V10AD1.zip file. It includes two files (CISP400V10AD1.cpp, and CISP400V10AD1.exe). The CISP400V10AD1.exe file is an executable file. You can double click the file to get to the expecting result of this assignment. The CISP400V10AD1.cpp is a driver program for you to use to test the implementation of this assignment. You need to create and finish coding the Employee.h(Employee class declaration) and Employee.cpp (the implementation of Employee class) based on the above specification. Put the Employee.h, Employee.cpp and the CISP400V10AD1.cpp (attached) in a project, you can compile the project and run to the following result. Please be awarded that you can adjust only your program to generate the required result but not the code in CISP400V10AD1.cpp file.
