Another class Overtime is declared as
Class Name Overtime
Data members
ndays : To store the number of days worked
ex_hrs : To store the number of hours worked per day
rate : Rate per hour
Member Functions
Overtime (int n, double r, int h) Constructor to assign n to ndays ,
r to rate anf h to ex_hrs
Double calculate() : to calculate the total salary(Number of days worked * rate per hour
* number of hours worked per day + basic salary) and total salary.
void show_salary() To display number of days worked rate and total salary.
Using the concept of inheritance define the above classes and all the
functions in them the main function need not to be written.
