How to Write a Copy Assignment Operator for CarCounter in C++?

[EvanET]

I am given a prompt to: Write a copy assignment operator for CarCounter that assigns objToCopy.carCount to the new objects's carCount, then returns *this.

#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  */

int main() {
   CarCounter frontParkingLot;
   CarCounter backParkingLot;

   frontParkingLot.SetCarCount(12);
   backParkingLot = frontParkingLot;

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

   return 0;
}

I cannot solve the code for it, I am stuck.

Hi EvanET! :D

We ask that our users show their progress (work thus far or thoughts on how to begin) when posting questions. This way our helpers can see where you are stuck or may be going astray and will be able to post the best help possible without potentially making a suggestion which you have already tried, which would waste your time and that of the helper.

Can you post what you have done so far?
