How would you create this program in c++ language with no global variables?

The Input file: Class members contributed employee data (name, integer ID, number of years of service, salary) and it in a file named staff.txt. A 4th data member, the employee ID, is to be added to the employee class definition. A company will use an array of employee objects to store employee data; the company plans to grow, so the array size will be larger than the actual number of people they employ. The declaration can be:

employee personnel[50];

The default constructor will initialize the 50 objects in the array. An input file has employee data which is read into variables such as strName, id, years, and pay, then an array object calls the class setData function with the variables as parameters:

personnel[index].setData(strName, id, years, pay);

The input function determines how many actual employees there are.

The output function has each array object call its print function.

This lab leads into Program 6, which will add processing to the array of employee objects.

The staff.txt is:

This project extends the labs on the class employee, done on April 11 and 13. Use your header file employee h which has four data members in the employee class (including empID), and has the setData function with parameters for each of the four data members of the class. For the lab, you developed a main program which declared an array of employee objects, called an input function to read employee data from an input file to put values in some of the array objects, and used a for loop to print the data in the objects that received input data. You will use these features, and extend the actions to be performed on the employee objects. Declare an array named personnel, consisting of employee objects. Call the input function to read in the array data from the input file staff.txt, as before. Then add functions as needed for a user-driven program to allow the user to Add an employee the user specifies the employee data by keyboard input Print all employees' data Print a particular employee's data-the user specifies the employee ID Give every employee a cost-of-living-allowance, by increasing the salary by 2% Have a Menu function which presents these choices to the user, and returns the user's selection When the user's choice has been done, show the menu again and repeat: have the user end the program by selecting a Quit choice from the menu. (One example of a menu function is in the Candy Machine example at the end of the chapter on classes.)
