C++ Visual Studio 2019 Complete #13. Dependent #1 Employee and ProductionWorker classes showing below. Modify the Employee and ProductionWorker classes so they throw exceptions when the following errors occur: The Employee class should throw an exception named InvalidEmployeeNumber when it receives an employee number that is less than 0 or greater than 9999. The ProductionWorker class should throw an exception named InvalidShift when it receives an invalid shift. The ProductionWorker class should throw an exception named InvalidPayRate when it receives a negative number for the hourly pay rate. Write a driver program that demonstrates how each of these exception conditions works. #1 Employee and ProductionWorker classes #include <string>#include <iostream>#include <iomanip>using namespace std; class Employee{private: string name; // Employee name string number; // Employee number string hireDate; // Hire date public: // Default…

use C++ programing language Write a program that prompts the user to enter a person's date of birth in numeric form such as 8-27-1980. The program then outputs the date of birth in the form: August 27, 1980. Your program must contain at least two exception classes: invalidDay and invalidMonth. If the user enters an invalid value for day, then the program should throw and catch an invalidDay object. Similar conventions for the invalid values of month and year. (Note that your program must handle a leap year.)
