/*This program illustrates use of constructor in inheritance.That is it is mandatory to use constructor in derived class if base class have constructor.So how many arguments should be passed to it.The ans is no of arguments required for base class + that required for derived class. YOU can see this in the following program.
design a class called Account having customer information.
derive a class called Savings from Account class, which
have additional data member called years of deposit.
interest is calculated at 8.75% rate and given on total
years of deposit.
Derive another class called Current from Account
class,which does not provide any interest on deposit.
Use appropriate member functions and constructors.
