Copied is my previous code, I am struggling to implement the new code. Please assist.

//main.cpp#include #include "bankAccount.h"using namespace std;// Initialize static member "nextaccountnumber" of class bankAccountint bankAccount::nextaccountnumber = 1000;//Declare a constconst int CUSTOMER_COUNT = 10;//main functionint main(){//Declaring an array of 10 components of type bankAccount.bankAccount myaccounts[CUSTOMER_COUNT]; //getting customer information from userfor(int index = 0; index > balance; //get interest ratecout > interestrate;//creating object and adding it to arraymyaccounts[index] = bankAccount(holdername, accounttype, balance, interestrate);cin.ignore();}//Iterating the array and printing all the customer informationcout

Please see below instructions for programming exercise:
 
 service charge applied. Derive class savingsAccount from base class bankAccount. The savingsAccount class should define and implement the following data and methods: savingsAccount Data Methods interestRate getInterestRate setinterestRate withdraw postinterest print Constructor: sets account number sets account balance set interest rate NOTES: Withdraw checks to make sure there is enough money before altering the balance. If not, a warning message is printed and the balance remains unchanged. Create a main program to test the class as follows. Use hard coded data (do not prompt the user for data, just make up values). Perform these steps in order: 1. create 2 checking accounts and 2 savings accounts 2. deposit money in each 3. post interest in each 4. print details of each 5. write checks in the checking accounts 6. withdraw from the savings accounts 7. print details of eachYou will create seven files for this assignment: bankAccount.h (base class definition) bankAccount.cpp (base class implementation) checkingAccount.h (checkingAccount definition) checkingAccount.cpp (checkingAccount implementation) savingsAccount.h (savingsAccount definition) savingsAccount.cpp (savingsAccount implementation) bankAccountTest.cpp (test file for your bankAccount class)
