C++

You operate several hot dog stands distributed throughout town and need to track sales.

Define a class named HotDogStand

has a member variable for the hot dog stand's ID number and a

has a member variable for how many hot dogs the stand has sold that day.

has a constructor that allows a user of the class to initialize both values.

has a function named "JustSold"

increments the number of hot dogs the stand has sold by one.

(this method will be invoked each time the stand sells a hot dog)

has a function that returns the number of hot dogs sold.

has a static variable called totalDogs that tracks the total number of hotdogs sold by all hot dog stands (should be updated as part of each sale)

has a static function that returns the value of totalDogs

Write a main function that will:

Welcomes

create 3 hotdog stands

initialize the stands to the ids 1,2,3

initialize sales to 0

display the current sales for each stand

display totalDogs

invoke the JustSold function once for each stand

display the current sales for each stand

display totalDogs

Use 3 loops to:

invoke JustSold 123 times for stand 1

invoke JustSold 101 times for stand 2

invoke JustSold 134 times for stand 3

display the current sales for each stand

display totalDogs

Goodbye

Explanation / Answer

Hi,

Please find my working code.

#include <iostream>

using namespace std;

//Class definition
class HotDogStand
{
    //Private variables
    private:
        static int tSold;
        int idNum;
        int soldNum;

//Public members
public:

        //Constructor
        HotDogStand(int id, int sold)
        {
            idNum = id;
            soldNum = sold;
        }

        //Function that increments sold number
        void justSold()
        {
            soldNum += 1;
            tSold += 1;
        }

        //Function that returns id
        int getID()
        {
            return idNum;
        }

        //Function that returns sold number
        int getNumSold()
        {
            return soldNum;
        }

        //Function that returns total number sold
        static int getTotalSold()
        {
            return tSold;
        }
};

//Initializing static variable
int HotDogStand::tSold = 0;

//Main function
int main()
{
//Creating objects
HotDogStand s1(1,0), s2(2,0), s3(3,0);

    //Updating items sold
    s1.justSold();
    s2.justSold();
    s1.justSold();

    //Printing current status
    cout << "Stand " << s1.getID() << " sold " << s1.getNumSold() << endl;
    cout << "Stand " << s2.getID() << " sold " << s2.getNumSold() << endl;
    cout << "Stand " << s3.getID() << " sold " << s3.getNumSold() << endl;

//Printing total sold
cout << endl << "Total sold = " << s1.getTotalSold() << endl;

cout << endl;

    //Updating items sold
    s3.justSold();
    s1.justSold();

//Printing total sold
cout << endl << "Total sold = " << s1.getTotalSold() << endl;

return 0;
}
