Question

Write a copy assignment operator for CarCounter that assigns objToCopy.carCount to the new objects's carCount, then returns *this. Sample output for the given program:
Cars counted: 12
#include
using namespace std;

class CarCounter {
public:
CarCounter();
CarCounter& operator=(const CarCounter& objToCopy);
void SetCarCount(const int setVal) {
carCount = setVal;
}
int GetCarCount() const {
return carCount;
}
private:
int carCount;
};

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

// FIXME write copy assignment operator

/* Your solution goes here */

int main() {
CarCounter frontParkingLot;
CarCounter backParkingLot;

frontParkingLot.SetCarCount(12);
backParkingLot = frontParkingLot;

cout << "Cars counted: " << backParkingLot.GetCarCount();

return 0;
}

Answer 1

The following cose will be used to copy assignment operator for CarCounter

Explanation:

Complete Program:

#include <iostream>

using namespace std;

class CarCounter

{

public:

CarCounter();

CarCounter& operator=(const CarCounter& objToCopy);

void SetCarCount(const int setVal)

{

 carCount = setVal;

}

int GetCarCount() const

{

 return carCount;

}

private:

int carCount;

};

CarCounter::CarCounter()

{

carCount = 0;

return;

}

// FIXME write copy assignment operator

/* Your solution goes here */

CarCounter& CarCounter::operator=(const CarCounter& objToCopy)

{

if(this != &objToCopy)

 carCount = objToCopy.carCount;

return *this;

}

int main()

{

CarCounter frontParkingLot;

CarCounter backParkingLot;

frontParkingLot.SetCarCount(12);

backParkingLot = frontParkingLot;

cout << "Cars counted: " << backParkingLot.GetCarCount();

cout << endl << endl;

system("pause");

return 0;

}
