Answer:
Following are the code to this question:
CarCounter::~CarCounter()//Defining destructor CarCounter
{
cout << "Destroying CarCounter\n";//print message Destroying CarCounter
}
Explanation:
Following are the full program to this question:
#include <iostream>//Defining header file
using namespace std;
class CarCounter //Defining class CarCounter
{
public:
CarCounter();//Defining constructor CarCounter
~CarCounter();//Defining destructor CarCounter
private:
int carCount;//Defining integer variable carCount
};
CarCounter::CarCounter()//declaring constructor
{
carCount = 0;//assign value in carCount variable
return;//using return keyword
}
CarCounter::~CarCounter()//Defining destructor CarCounter
{
cout << "Destroying CarCounter\n";//print message Destroying CarCounter
}
int main() //Defining main method
{
CarCounter* parkingLot = new CarCounter();//Defining class object parkingLot
delete parkingLot;//
return 0;
}
- In the given C++ language code, a class "CarCounter" is defined, and inside the class, a "constructor, Destructors, and an integer variable" is defined.
- Outside the class, the scope resolution operator is used to define the constructor and assign value "0" in the integer variable.
- In the above-given code, the scope resolution operator, to define destructor and inside this cout function is used, which prints a message.
- In the main method, the class object is created, which automatically calls its class constructor and destructors.
