Assume the existence of a BankAccount class. Define a derived class, SavingsAccount that contains two instance variables: the first a double, named interestRate, and the second an integer named interestType. The value of the interestType variable can be 1 for simple interest and 2 for compound interest. There is also a constructor that accepts two parameters: a double that is used to initialize the interestRate variable, and a string that you may assume will contain either "Simple", or "Compound", and which should be used to initialize the interestType variable appropriately. There should also be a pair of functions getInterestRate and getInterestType that return the values of the corresponding data members (as double and int respectively).

Class SavingsAccount : public BankAccount

{

double interestRate;

int interestType;

public SavingsAccount (double interestRate, string interestType)

{

this. interestRate=interestRate;

if (interestType=="Simple")

this. interestType=1;

else if (interestType=="Compound")

this. interestType=2;

}

public double getInterestRate ()

{

return this. interestRate;

}

public int getInterestType ()

{

return this. interestType;

}

}
