Question

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).

I need the code written in C++.

Explanation / Answer

// Derived class
class SavingsAccount: public BankAccount {
public:
double interestRate;
int interestType;

SavingsAccount(double irate, string itype) {

   interestRate=irate;
   if (itype == 'Simple')
   {
       interestType=1;
   }
   else if(itype == 'Compound')
   {
       interestType=2;
   }
}
double getinterestRate() {
return interestRate;
}
int getinterestType() {
return interestType;
}
};
