Question

Create a driver class to do the following:

a.

Read data from the given file BankData.data and create and array of BankAccount Objects

The order in the file is first name, last name, id, account number, balance. Note that account

name consists of both first and last name

b.

Print the array (without account id) the account balance must

show only 2 decimal digits. You will need to do some string processing.

c.

Find the account with largest balance and print it

d.

Find the account with the smallest balance and print it.

e.

Determine if there are duplicate accounts in the array. If there are then set the duplicate account

name to XXXX XXXX and rest of the fields to 0. Note it’s hard to “delete” elements from an array.

Or add new accounts if there is no room in the array. If duplicate(s) are found, print the array.

Main.cpp

#include <iostream>
#include <fstream>
#include <string>
#include //your header file

using namespace std;
const int SIZE = 8;
void fillArray (ifstream &input,BankAccount accountsArray[]);
int largest(BankAccount accountsArray[]);
int smallest(BankAccount accountsArray[]);
void printArray(BankAccount accountsArray[]);
int main() {

   //open file
   //fill accounts array
   //print array
   //find largest
   //find smallest
   //find duplicates and print if necessary
BankAccount accountsArray[SIZE];

    fillArray(input,accountsArray);
    printArray(accountsArray);
    cout<<"Largest Balance: "<<endl;
    cout<<accountsArray[largest(accountsArray)].toString()<<endl;
    cout<<"Smallest Balance :"<<endl;
    cout<<accountsArray[smallest(accountsArray)].toString()<<endl;
}
}
void fillArray (ifstream &input,BankAccount accountsArray[]){

}

int largest(BankAccount accountsArray[]){
//returns index of largest account balance
}
int smallest(BankAccount accountsArray[]){
//returns index of smallest

}
BankAccount removeDuplicate(BankAccount account1, BankAccount account2){

return (account1.equals(account2));

}
void printArray(BankAccount accountsArray[]){
   cout<<" FAVORITE BANK - CUSTOMER DETAILS "<<endl;
   cout<<" --------------------------------"<<endl;
//print array using to string method

}
