Hello, I'm working on a C++ project and am getting a few errors here, mostly need help with the loadArray function and the look up taxes function. Here is my code so far:

#include
#include
#include
#include
using namespace std;

//Functions
void displayAddressesAmtDue(string[], double[], int);
void sortDisplayAddressTaxDue(string[], double[], int);
void lookUpTaxes(string[], double[], int);
void displayLargestDelTaxBill(string[], double[], int);
void loadArrays(string[], double, int &);
//globals
const int SIZE = 7;
string address[7];
double amtDue[7];

int loadArrays(string address[], double amtDue[], int length)
{
    int count = 0;
    ifstream loadTaxes;
    loadTaxes.open("prog3.txt");
   if (loadTaxes.fail()) {
        // this will alert user if there is a problem opening the file
        cout << "Error opening the file ";
        return 0;
    }
    for (int i = 0; i < length; i++)
    {
        std::getline(loadTaxes >> std::ws ,address[i]);
        loadTaxes >> amtDue[i];
        cout << address[i] << endl;
        cout << "$" << amtDue[i] << endl;
    }
}
//Show menu function
void showMenu()
{
int choice; //menu choice
do
{
//display menu
cout << "----------------------------------------------------------- ";
cout << "County Auditor Database Search Menu: ";
cout << endl;
cout << "Enter 1 = All Taxes and Properties "

cout << "----------------------------------------------------------- ";
cin >> choice;
cout << endl;

//validate user's choice
while (choice < 1 || choice > 5)
{
cout << "Enter a valid selection: ";
cin >> choice;
}

//process user's choice
if (choice != 5)

//respond with user's menu selection
switch (choice)
{

}

Explanation / Answer

Given below is the fixed code.

1. Removed all globals since it is not a good practice. Used those variables inside showMenu()

2. Also instead of fixing the number of records to 7, made changes to program so that it will figure out how many records were present when EOF was reached

3. Fixed sorting and finding largest due code

Hope it helps. If it does , please don't forget to rate the answer. Thank you very much.
