Question

C ++

Modify the PetHotel code on blackboard to:

1. Add a line of stars below the menu, use the same method that is in the code. This is called “code reuse.” Functions/Methods allow us to do that.
2. Add a 4^th option for parrots – they cost $3.
3. Modify the code so the total is calculated within the printMenu method and returned to the main method. Modify the name of the “prinMenu” method so the it is appropriate.

#include <iostream>

using namespace std;

int printMenu();

int enterNights();

void drawLine();

int main() {

    int nights;

    int total;

    int menu_option;

    int net_total;

   

    //enter nights

    nights = enterNights();

   

    //print the menu and enter option and calculate total

    do {

       //printMenu

        drawLine();

        menu_option = printMenu();

        if (menu_option == 1)

            total = total + 5;

        else if (menu_option==2)

            total = total + 10;

        else if (menu_option==3)

            total = total + 4;

        else if ((menu_option>4) || (menu_option<1))

            cout<<"Invalid Option"<<endl;

    } while (menu_option!=4);

   

   //calculate the net_total

    net_total = total * nights;

    cout<<"Total is: $"<<net_total;

}

void drawLine() {

    cout<<"***********************"<<endl;

}

int printMenu() {

    int menu_option;

    cout<<"Boarding prices"<<endl;

    cout<<"1. Small Dog"<<endl;

    cout<<"2. Big Dog"<<endl;

    cout<<"3. Cat"<<endl;

    cout<<"4. Quit"<<endl;

    cout<<"Enter option: ";

   

    cin>>menu_option;

    return menu_option;

}

int enterNights() {

    int nights;

    cout<<"Enter the number of nights: ";

    cin>>nights;

    return nights;

}

thanks for the question.

Here is the completed code for this problem. Comments are included, go through it, learn how things work and let me know if you have any doubts or if you need anything to change.If you are satisfied with the solution, please rate the answer.

Changes to the existing code are commented so that you can understand the changes.

printMenu() function renamed as getPetTotal()
