Ans. program code :

#include<iostream>
#include<stdlib.h>
using namespace std;
class bank
{
int ac,bal;
static int reset_t;
float balance, amount, shorta;
public:
// declaring methods
void deposit();
void withdraw();
void chkbalance();
void interestRate();
int menu();
};
int bank::reset_t=0;
//defining the methods
void bank::deposit()
{
cout<<"\n Enter Account Number:";
cin>>ac;
if(ac==1001)
{
cout<<"\nEnter Amount you want to Deposit:";
cin>>amount;
balance=balance+amount;
cout<<"\n\nMessage: You have successfully deposited Rs."<<amount<<" into your account.\n\nYour Current Balance is:"<<balance<<"\n\n";
reset_t++;
}
else
{
cout<<"You have entered invalid account number";
}
}
void bank::withdraw()
{
cout<<"Enter Account Number:";
cin>>ac;
if(ac==1001)
{
cout<<"Enter Amount you want to Withdraw:";
cin>>amount;
if(amount>balance)
{
shorta=amount-balance;
cout<<"\n\nYou cannot withdraw Rs."<<amount<<" as your account balance is Rs."<<balance<<"\n\nYou are short of Rs."<<shorta;
}
else
{
balance=balance-amount;
cout<<"You have Withdrawn Rs."<<amount<<" Successfully\n\n Your account balance is:"<<balance<<"\n\n";
}
}
else
{
cout<<"You have entered invalid account number";
}
}
void bank::chkbalance()
{
cout<<"Enter Account Number:";
cin>>ac;
if(reset_t==0)
{
balance=0;
}
if(ac==1001)
{
cout<<"Your Account balance is Rs."<<balance<<"\n\n";
}
else
{
cout<<"Account Doesn't Exist!!";
}
}
void bank::interestRate()
{
   cout<<"Enter Account Number:";
cin>>ac;
if(reset_t==0)
{
balance=0;
}
if(ac==1001)
{
cout<<"Your Account balance is Rs."<<2*balance<<"\n\n";
}
else
{
cout<<"Account Doesn't Exist!!";
}
}

int main()
{
bank ob;
int ch,value;
//showing the type of account
cout<<"\n enter the type of account";
cout<<"\n 1: savings";
cout<<"\n 2: checking account";
cout<<"\n 3: money market account";
cout<<"\n";
cin>>value;
  
do {
//dispalying menu to user
cout<<"\n\n\n1.Deposit\n2.Withdraw\n3.Balance Enquiry\n4.calculate interest\n5.Exit\n\n";
ch=ob.menu();
switch(ch)
{
case 1:ob.deposit(); // case for depositing amount
break;
case 2:ob.withdraw(); //case for withdrawing amount
break;
case 3:ob.chkbalance(); //case to check balance
break;
case 4: ob.interestRate(); //case to find teh interest rate
break;
case 5: exit(1);
default:cout<<"Invalid Choice!!"; //showing default message to user
}
}while(1);
}

int bank::menu()
{
int ch;
cout<<"\nEnter your Choice:";
cin>>ch;
return ch;
}
