Question

In C++

Write a program that contains a BankAccount class.

The BankAccount class should store the following attributes:

account name

account balance

Make sure you use the correct access modifiers for the variables.

Write get/set methods for all attributes.

Write a constructor that takes two parameters.

Write a default constructor.

Write a method called Deposit(double) that adds the passed in amount to the balance.

Write a method called Withdraw(double) that subtracts the passed in amount from the balance. Do not allow a balance < 0.

Write a method called Printit() that prints all of the attribute values.

Inside of main() create one instance of the BankAccount class. Make sure you call Deposit and Withdraw. Finally, print out the values on the instance you created.

Derive a new class called SavingsAccount from the BankAccount class.(Savings inherits from BankAccount)

SavingsAccount should store the following new attribute: interest.

Write get/set methods for all attributes.

Write a constructor that takes three parameters. Make sure to call the base class constructor.

Write a default constructor.

Write a method called ApplyInterest() that will apply the interest amount to the balance.

Inside of main() create one instance of the SavingsAccount class. Make sure you call Deposit, Withdraw, ApplyInterest. Finally, print out the values on the instance you created.

Derive a new class - Customer Class (Inherits from Savings – savings inherits from bank account)

Write a customer class. Customer Class has the following new attribute

Customer Name

Write get/set methods for the Name attribute.

Create WithdrawSavings and DepositSavings methods. These methods should call methods on the Savings account and the Bank account members.

Create an instance of the Customer class in main. Make sure you set values on that instance. Print the values of the Customer on standard output.

Code:

#include
using namespace std;
class BankAccount
{
string name;
double balance;
public:
//default constructor
BankAccount()
{
name="";
balance=0;
}
BankAccount(string s, double bal)
{
name=s;
balance=bal;
}
string getname()
{
return name;
}
double getbalance()
{
return balance;
}
void setname(string s)
{
name=s;
}
void setbalance(double bal)
{
balance=bal;
}
void Deposit(double bal)
{
cout<<"\nDepositing "< balance=balance+bal;
}
void Withdraw(double wd)
{
if(balance -wd <=0 )
{
cout<<"Sorry no sufficient balance ";
}
else

{cout<<"\nWithdrawing "< balance=balance-wd;}
}
void Printit()
{
cout<<"\nAccount name is "< cout<<"\nbalance is "< }

};

class SavingsAccount : public BankAccount
{
double interest;
public:

SavingsAccount():BankAccount()
{
interest=0;
}
SavingsAccount(string s, double bal, double itr):BankAccount(s,bal)
{
interest=itr;
}
double getinterest()
{
return interest;
}
void setinterest(double itr)
{
interest=itr;
}
void ApplyInterest()
{
double t=getbalance();
t=t+t*getinterest()/100;
setbalance(t);
}
void Printit()
{
BankAccount::Printit();
cout<<"\nInterest is "< }

};

class Customer:public SavingsAccount
{
string custname;
public:
Customer(string s):SavingsAccount("Saving",0,0)
{
custname=s;
}
Customer():SavingsAccount("Saving",0,0)
{

custname="Default";
}
Printit()
{
cout<<"\nCustomer name is:"< SavingsAccount::Printit();
}
string getname()
{
return custname;
}
void setname(string n)
{
custname=n;
}
void Withdraw(double wd)
{
SavingsAccount::Withdraw(wd);
}
void Deposit(double bal)
{
BankAccount::Deposit(bal);
}
};
int main()
{
BankAccount b;
b.setname("xyz");
b.setbalance(100);
b.Deposit(10);
b.Withdraw(20);
b.Printit();

SavingsAccount s;
s.setname("abc");
s.setbalance(200);
s.setinterest(6);
s.Deposit(300);
s.Withdraw(200);
s.ApplyInterest();
s.Printit();

Customer c;
c.setname("ga_cust");
c.setbalance(200);
c.setinterest(7);
c.Withdraw(100);
c.Deposit(300);
c.Printit();

return 1;
}

Output:
