Question
You operate several hot dog stands distributed throughout town. Define a class named HotDogStand that has a member variable for the hot dog stand’s ID number and a member variable for how many hot dogs the stand sold that day. Create a constructor that allows a user of the class to initialize both values.
Also create a function named JustSold that increments the number of hot dogs the stand has sold by one. This function will be invoked each time the stand sells a hot dog so that you can track the total number of hot dogs sold by the stand. Add another function that returns the number of hot dogs sold.
Finally, add a static variable that tracks the total number of hot dogs sold by all hot dog stands and a static function that returns the value in this variable. Write a main function to test your class with at least three hot dog stands that each sell a variety of hot dogs.
Answer
#include <iostream>
#include<cstdlib>
using namespace std;
class HotDogStand
{
private:
int IDnumber;
int HotDogsSold;
static int totalSold;
public:
HotDogStand();
HotDogStand(int IDnumber, int hotDogsSold);
int getID();
void setID(int ID);
void JustSold();
int getNumSold();
static int getTotalSold();
};
int HotDogStand::totalSold=0;
int main()
{
HotDogStand a(1,0);
HotDogStand b(2,0);
HotDogStand c(3,0);
HotDogStand d;
a.setID(1);
b.setID(2);
c.setID(3);
a.JustSold();
b.JustSold();
a.JustSold();
cout<<"Id "<<a.getID()<<" sold "<<a.getNumSold()<<endl;
cout<<"Id "<<b.getID()<<" sold "<<b.getNumSold()<<endl;
cout<<"Id "<<c.getID()<<" sold "<<c.getNumSold()<<endl;
cout<<"Total sold="<<a.getTotalSold()<<endl;
system("PAUSE");
return 0;
}
HotDogStand::HotDogStand()
{
IDnumber=0;
HotDogsSold=0;
}
HotDogStand::HotDogStand(int IDnumber, int hotDogsSold)
{
IDnumber=IDnumber;
HotDogsSold=hotDogsSold;
}
int HotDogStand::getID()
{
return IDnumber;
}
void HotDogStand::setID(int newID)
{
IDnumber=newID;
}
void HotDogStand::JustSold()
{
HotDogsSold++;
totalSold++;
}
int HotDogStand::getNumSold()
{
return HotDogsSold;
}
int HotDogStand::getTotalSold()
{
return totalSold;
}
Output:
