/*Define a class Person with the following members
Data Members
Name of the person, age of the person and gender of the person
Member functions
read() - to read values to the data members
disp() - To display values of the data members
One default constructor and one overloaded constructor for Person class
Define a class Worker which inherits from Person class with the following
specification

Data members of Worker class
No.of hours worked per day and wage per hour

Member functions of Worker class
read() - to read values to the data members
calcwg() - to calculate the wage of a worker and return the value
extraWage() - if the twage of the worker is less than Rs. 200, then an extra
amount of Rs. 150 will be paid to the worker. Otherwise Rs. 50
will be paid.
TotalWage() - To find the total wage of the worker.
One default constructor and one overloaded constructor for worker class.
Overloaded constructor has to pass parameters to the parent class constructor.
display() - to display the values of the data members and the total wage
as shown below.
Output format
Name of the worker :
Age of the worker
No. Of Hours worked :
Wage per Hour :
Wage of the worker :
Extra wage :
Total Wage*/
