Multiple Bools

[reubenfs]

I can't figure out why my bool values aren't getting passed on correctly. I have two bools, one for "sunRoof" and another for "autoTrans".

Client.cpp

#include <iostream>
#include <cstdlib>
using namespace std;

#include "vehtypes.h"

int main()
{
   Car   c1( "Ford", 10000, "Mustang", false ),
         c2( "Chevy", 15000, "Camaro", true );
   Truck t1( "Ford", 12000, 1.5, true ),
         t2( "Dodge", 14000, 2.0, false );

   cout << "Dealer inventory:" << endl << endl;
   c1.showVehicle();
   c2.showVehicle();
   t1.showVehicle();
   t2.showVehicle();

   system("PAUSE");
   return 0;
}

Vehicle.h

#ifndef _VEHICLE
#define _VEHICLE

#include <iostream>
#include <iomanip>
#include <string>
using namespace std;

class Vehicle
{
   public:
      Vehicle( string mfg, double cost )
         { mfgName = mfg;
           dealerCost = cost;
         }
      ~Vehicle()
         {  } 
      double retailPrice(void)
         { return dealerCost * 1.25; }
      void showVehicle(void)
         { cout << "Manufacturer:   " << mfgName << endl
                << "Customer price: " 
                << fixed << showpoint << setprecision(2)
                << retailPrice() << endl;
         }      
   private:
      string mfgName;
      double dealerCost;
};

Car::Car(string mfg, double cost, string model, int sun)
   :Vehicle(mfg, cost)
   {
      modelName = model;
      int sunRoof = sun;
   }

sunRoof here is a local variable so sun is never assigned to the class member. (also sunroof in not a bool)

You have the same with truck.
Try:

Car::Car(string mfg, double cost, string model, int sun)
   :Vehicle(mfg, cost), modelName(model),sunRoof(sun)
   {

   }

and

Truck::Truck(string mfg, double cost, double capacity, bool autoTrans)
     :Vehicle(mfg, cost), capacityTons(capacity),autoTrans(autoTrans)
     {

      }
