Question

Use this code to create multiple functions.

#include<iostream>

#include<iomanip>

#include<fstream>

using namespace std;

int main()

{

cout << fixed << showpoint << setprecision(2);

ofstream outFile;

outFile.open("Feras's.txt");

outFile << "..Skinny Feras's Restaurant ..\n\n" << endl;

int choise=10, quantity;

float paid, SubTotal=0, Tax = .10, Total, RM, more;

while(choise!=0)

{

system("cls");

cout << "\t**Welcome To Skinny Alsaif Restaurant Lol**" << endl;

cout << "\nWhat would you like to have?" << endl;

cout << "1. Burger." << endl;

cout << "2. Pizza." << endl;

cout << "3. Rize With Chickens." << endl;

cout << "4. Spaghetti." << endl;

cout << "5. Steak." << endl;

cout << "6. Apple pie." << endl;

cout << "7. Tea." << endl;

cout << "8. Coffee." << endl;

cout << "9. Salad." << endl;

cout << "10.Meat." << endl;

cout << "Subtotal: $" << SubTotal << endl;

cout << "Please Enter 0 whenever you are ready :)" << endl;

cout << "choise: ";

cin >> choise;

if (choise!=0)

{

cout << "Enter quantity: ";

cin >> quantity;

}

if(choise== 1)

SubTotal = SubTotal + (2.40 * quantity);

else if (choise == 2)

SubTotal = SubTotal + (5.99 * quantity);

else if (choise == 3 ||choise == 4)

SubTotal = SubTotal + (4.90 * quantity);

else if (choise == 5 || choise== 6 )

SubTotal = SubTotal + (6.79 * quantity);

else if (choise == 7 || choise== 8 )

SubTotal = SubTotal + (3.99 * quantity);

else if (choise == 9 || choise== 10 )

SubTotal = SubTotal + (7.50 * quantity);

}

system("cls");

cout << "\n\n*5SubTotal $" << SubTotal << endl;

cout << "*Tax $" << SubTotal * Tax << endl;

Total = SubTotal + (SubTotal * Tax);

cout << "*Total $" << SubTotal + (SubTotal * Tax) << endl;

cout << "*Enter Payment Amount $";

cin >> paid;

while(paid < Total)

{

system("cls");

cout << "\n\n*You did not paid enough" << endl;

cout << "*Amount paid $" << paid << " Total $" << Total << endl;

cout << "*Enter Payment Amount $";

cin >> more;

paid = paid + more;

}

if(paid >= Total)

RM = paid - Total;

outFile << "SubTotal $" << SubTotal << endl;

outFile << "Tax $" << Tax << endl;

outFile << "Total $" << Total << endl;

outFile << "Change due $" << paid - Total << endl;

cout << "*Change Due $" << RM << endl;

cout << "\nHave a Nice Day " << endl;

outFile.close();

system("pause");

return 0;

}

Use your code from the menu system created back in March so that it uses multiple functions. You should create as many functions as possible for this assignment. In addition, I would like to see the usage of arrays in your program where appropriate. This is not required, but strongly encouraged.
