Question

Write a destructor for the CarCounter class that outputs the following. End with newline.

Answer 1

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.
