5. void withdraw(double amount): function which withdraws an amount from accountBalance
6. void deposit(double amount): function which deposits an amount to the accountBalance.

Code

#include<iostream>

using namespace std;
class BankAccount
{
private:
   double accountBalance;
   double interestRate;
   int accountId;
public:
   static int count;
   BankAccount(double,double);
   void withdraw(double);
   void deposit(double);
   void calculateMonthlyInterest();
   void displayAccountInfo();
};
int BankAccount::count=0;
BankAccount::BankAccount(double balance,double rate)
{
   accountBalance=balance;
   interestRate=rate;
   accountId=101+count;
   count++;
}
void BankAccount::withdraw(double amount)
{
   if(amount>accountBalance)
   {
       cout<<"Insufficient balance."<<endl;
       return;
   }
   else
   {
       accountBalance-=amount;
   }
}
void BankAccount::deposit(double amount)
{
   accountBalance+=amount;
}
void BankAccount::calculateMonthlyInterest()
{
   accountBalance+=accountBalance*(interestRate/100);
}
void BankAccount::displayAccountInfo()
{
   cout<<"Account ID: "<<accountId<<endl;
   cout<<"Account Balance: $"<<accountBalance<<endl;
   cout<<"Intrest Rate: "<<interestRate<<"%"<<endl;
   cout<<"Number of account created: "<<count<<endl<<endl;
}
int main()
{
   BankAccount ba1(1000,4.5);
   BankAccount ba2(2000,6.5);

   cout<<"Initially account is "<<endl;
   ba1.displayAccountInfo();
   ba2.displayAccountInfo();

   ba1.deposit(200);
   ba2.deposit(500);
  
   cout<<"\nAfter deposite account is"<<endl;
   ba1.displayAccountInfo();
   ba2.displayAccountInfo();

}
