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:

[C++ Warning] Ex6_2.cpp(4): W8058 Cannot create pre-compiled header: write failed
[C++ Error] Ex6_2.cpp(34): E2040 Declaration terminated incorrectly
[C++ Error] Ex6_2.cpp(44): E2040 Declaration terminated incorrectly

[C++ Error] Ex6_2.cpp(44): E2190 Unexpected }
[C++ Error] Ex6_2.cpp(68): E2448 Undefined label 'tollBooth2'

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.

Declaration terminated incorrectly

means that a declaration is declared incorrectly

Unexpected }

Means that you have an extra/missing { or }

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.
