and here are my codes

#include <iostream>

#include <string>

#include <iomanip>

#include <cmath>

using namespace std;

double Item_Pick();

int main()

{

double payemant;

int numItem, choise{};

int item, loop = {}, cont;

cont = 0;

choise = 0;

double Item_Pick();

item = Item_Pick();

while (choise != 8)

{

cout << "\nEnter your choice from the menu below:";

cout << "\n1) Gyro $7.00";

cout << "\n2) Moussaka $8.50";

cout << "\nEnter your menu choice>";

cin >> item;

cont++;

}

cout << endl << endl;

system("pause");

return 0;

}

double Item_Pick()

{

int choice{}, numItem;

string itemName;

double itemPrice, tax, tip;

const double TAX_RATE = .065;

const double TIP_RATE = .20;

switch (choice)

{

case 1:

itemName = "Gyro";

itemPrice = 7;

break;

case 2:

itemName = "Moussaka";

itemPrice = 8.50;

break;

case 3:

itemName = "Salad";

itemPrice = 3.75;

break;

case 4:
