What do I need to do?

Okay I am writing a program that is called tollbooth and I had to add a second tollbooth to it. But why does my code not work?

Code:

---

// ex6_2.cpp
// uses class to model toll booth
#include <iostream>
using namespace std;
#include <conio.h>

const char ESC = 27;          //escape key ASCII code
const double TOLL = 0.5;      //toll is 50 cents
////////////////////////////////////////////////////////////////
class tollBooth
  {
  private:
      unsigned int totalCars;      //total cars passed today
      double totalCash;            //total money collected today
  public:                        //constructor
      tollBooth() : totalCars(0), totalCash(0.0)
        {  }
      void payingCar()                        //a car paid
        { totalCars++; totalCash += TOLL; }
      void nopayCar()                          //a car didn't pay
        { totalCars++; }
      void display() const                    //display totals
        { cout << "\nCars=" << totalCars
                << ", cash=" << totalCash
                << endl; }
    };
//---------------------------------------------------------------------
class tollBooth2
  {
  private:
      unsigned int totalCars;  //total cars passed today
      double totalCash;        //total money collected today
  public:                    //constructor
      tollBooth() : totalCars(0), totalCash(0.0)
        {  }
      void payingCar()                      //a car paid
        { totalCars++; totalCash += TOLL; }
      void nopayCar()                        //a car didn't pay
        { totalCars++; }
      void display() const                  //display totals
        { cout << "\nCars=" << totalCars
                << ", cash=" << totalCash
                << endl; }
    };
//---------------------------------------------------------------------

int main()
  {
  tollBooth booth1, booth2;          //create a toll booth
  char ch;

  cout << "\nPress 0 for each non-paying car,"
        << "\n      1 for each paying car,"
        << "\n      2 to go to second tool booth,"
        << "\n      Esc to exit the program.\n";
  do {
      ch = getche();          //get character
      if( ch == '0' )          //if it's 0, car didn't pay
        booth1.nopayCar();
      if( ch == '2' )
        goto tollBooth2;
      if( ch == '1' )          //if it's 1, car paid
        booth1.payingCar();
      } while( ch != ESC );    //exit loop on Esc key
  booth1.display();          //display totals
  getch();
  return 0;
  }

Here are the errors:

What do I do?


Code Tags changed from [ Quote ] tags by Kermi3....good effort :).

Insteed of using quote-tags use code tags ( [ code ] [ /code] , without blank spaces) because it´s easer to "follow" the code.

Quote:

---

Declaration terminated incorrectly

---

means that a declaration is declared incorrectly

Quote:

---

Unexpected }

---

Means that you have an extra/missing { or }

Quote:

---

Undefined label 'tollBooth2'

---

You haven´t declared a label named 'tollBooth2'.

Quite self explaning :)

Hope that it helps and don´t forget to use code tags, the formating is so much better.

hi, try this one. Is it OK?

Code:

---

// ex6_2.cpp
// uses class to model toll booth
#include <iostream>
using namespace std;
#include <conio.h>

const char ESC = 27;          //escape key ASCII code
const double TOLL = 0.5;      //toll is 50 cents
////////////////////////////////////////////////////////////////
class tollBooth
  {
  private:
      unsigned int totalCars;      //total cars passed today
      double totalCash;            //total money collected today
  public:                        //constructor
      tollBooth() : totalCars(0), totalCash(0.0)
        {  }
      void payingCar()                        //a car paid
        { totalCars++; totalCash += TOLL; }
      void nopayCar()                          //a car didn't pay
        { totalCars++; }
      void display() const                    //display totals
        { cout << "\nCars=" << totalCars
                << ", cash=" << totalCash
                << endl; }
    };


int main()
  {
  tollBooth booth1, booth2;  //create a toll booth
  tollBooth *current_booth = &booth1;

  char ch;

  cout << "\nPress 0 for each non-paying car,"
        << "\n      1 for each paying car,"
        << "\n      2 to go to second tool booth,"
        << "\n      Esc to exit the program.\n";
  do {
      ch = getche();          //get character
      if( ch == '0' )          //if it's 0, car didn't pay
        current_booth->nopayCar();
      if( ch == '2' )
        current_booth = &booth2;
      if( ch == '1' )          //if it's 1, car paid
        current_booth->payingCar();
      } while( ch != ESC );    //exit loop on Esc key
  current_booth->display();          //display totals
  getch();
  return 0;
  }

[edit]Code tags added by Hammer. Please use them in future.

And as you probably know by now, "goto:" does not work like that! Besides, DON"T use them. They are fine constructs for ASM but have little value in this language...

In the class tollBooth2 you have defined the constructor wrong.

Code:

---

class tollBooth2
  {
  private:
      unsigned int totalCars;  //total cars passed today
      double totalCash;        //total money collected today
  public:                    //constructor
      //constructor should be
      //tollBooth2() : totalCars(0), totalCash(0.0)
      tollBooth() : totalCars(0), totalCash(0.0)
        {  }
      void payingCar()                      //a car paid
        { totalCars++; totalCash += TOLL; }
      void nopayCar()                        //a car didn't pay
        { totalCars++; }
      void display() const                  //display totals
        { cout << "\nCars=" << totalCars
                << ", cash=" << totalCash
                << endl; }
    };

Change this and the goto label and it should work. I would strongly advise you to listen to Sebastiani and don´t use goto unless you are absolutly sure that it works as intended.

Thank you very much. You all helped greatly.
