The program has a simple database support.

As a database file using a text file. Its structure is as follows:

name1
service1 *lenght of the employee work (f.e 2 years) etc.*
name2
service2
NAME3
service3

....

The program is able to add and display employee workers - in addition the program should allow for the statistical activities (calculation of the average length of service, finding the oldest employee). Additionally, the program should make it possible to edit and delete employees.

The program should use a function in the place of operations (for example a function for adding an employee, display, etc.)
