Challenge activity 8.10.1: Write a copy constructor.

Write a copy constructor for CarCounter that assigns origCarCounter.carCount to the constructed object's carCount. Sample output for the given program:

#include <iostream>
using namespace std;

class CarCounter {
public:
CarCounter();
CarCounter(const CarCounter& origCarCounter);
void SetCarCount(const int count) {
carCount = count;
}
int GetCarCount() const {
return carCount;
}
private:
int carCount;
};

CarCounter::CarCounter() {
carCount = 0;
return;
}

Explanation / Answer

#include <iostream>
using namespace std;
class CarCounter {
public:
CarCounter();
CarCounter(const CarCounter& origCarCounter);
  
void SetCarCount(const int count) {
carCount = count;
}
int GetCarCount() const {
return carCount;
}
private:
int carCount;
};

CarCounter::CarCounter() {
carCount = 0;
return;
}

CarCounter::CarCounter(const CarCounter& origCarCounter) {
carCount = origCarCounter.carCount;
return;
}

int main()
{
   CarCounter c1;
   cout<<"Enter the number of Cars:";
   int car;
   cin>>car;
   c1.SetCarCount(car);
   CarCounter c2=c1;
   cout<<"Cars Counted:"<<c2.GetCarCount();
   return 0;
}
