This project is to be done in C++

Design a generic class to hold the following information about a bank account: Balance . Number of deposits this month Number of withdrawals Annual interest rate The class should have the following member functions Constructor: accept arguments for balance and interest rate deposit: a virtual function that accepts an argument for the amount of the deposit withdrawal: a virtual function that accepts an argument for the amount of the withdrawal calclnt: a virtual function that updates the balance by calculating the monthly interest earned by the account, and adding this interest into the balance . Next, design a savings account class; derived from the generic account class, the savings account class should have the following members status (to represent an active or inactive account) If the balance of a savings account falls below $25, it becomes inactive. (The status member could be a flag variable.) No more withdrawals may be made until the balance is raised above $25, at which time the account becomes active again. The savings account class should have the following member functions withdraw: A function that checks to see if the account is inactive before a withdrawal is made. (No withdrawal will be allowed if the account is not active) a withdrawal is then made by calling the base class version of the function. .Deposit: a function that checks to see if the account is inactive before a deposit is made. If the account is inactive and then deposit brings the balance above $25, the account becomes active again. The deposit is then made by calling the base class version of the function.

Explanation / Answer

Answer:-

#include <iostream.h>
#include <conio.h>

class account
{
char cust_name[20];
int acc_no;
char acc_type[20];
public:
void get_accinfo()

}
void withdraw_currbal()
{
float penalty,withdraw;

}
elseif(withdraw > balance)

}
};

if(withdraw > savbal)
{
cout<<" You have to take permission for Bank Overdraft Facility ";
savbal=savbal+withdraw;
}
else

}
};

float cur_acct :: balance;
float sav_acct :: savbal;

void main()
{

cout<<"1) Deposit ";
cout<<"2) Withdraw ";
cout<<"3) Display Balance ";
cout<<"4) Display with full Details ";
cout<<"5) Exit ";

cin>>choice;
switch(choice)
{
case 1 : s1.deposit_savbal();
getch();
break;
case 2 : s1.withdraw_savbal();

break;
case 3 : s1.disp_savbal();
getch();
break;
case 4 : s1.display_accinfo();
s1.disp_savbal();
getch();
break;
case 5 : goto end;
default: cout<<" Entered choice is invalid,"TRY AGAIN"";
}
}
}
else
{
{
c1.get_accinfo();
while(1)
{
cout<<" Choose Your Choice ";
cout<<"1) Deposit ";
cout<<"2) Withdraw ";

break;
case 5 : goto end;

}
}
}
end:
}
}
