write a program to create a employee class EMP with data member(id, name address). Derive a class SALARY with data member(basicsal, post) and again derive class RECORD with data member(month, absent, total) and display employee complete information where total is calculated by deducing total "absent" days form "basicsal".

In this example, the 'EMP' class serves as the base class for the 'SALARY' and 'RECORD' classes, which are derived from it using the 'public' keyword. The 'SALARY' class adds the data members 'basicsal' and 'post', and the 'RECORD' class adds the data members 'month' , 'absent' and 'total' member is calculated by subtracting the 'absent' days form the 'basicsal'. The 'display()' function is used to display all the employee information.
