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

ycow [4]

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.

Write a program for determining if a year is a leap year. In the Gregorian calendar system you can check if it is a leaper if it

SOVA2 [1]

Answer:

def leap_year_check(year):

return if int(year) % 4 == 0 and (int(year) % 100 != 0 or int(year) % 400 == 0)

Explanation:

The function is named leap_year_check and takes in an argument which is the year which we wish to determine if it's a new year or not.

int ensures the argument is read as an integer and not a float.

The % obtains the value of the remainder after a division exercise. A remainder of 0 means number is divisible by the quotient and a remainder other wise means it is not divisible by the quotient.

If the conditions is met, that is, (the first condition is true and either the second or Third condition is true)

the function leap_year_check returns a boolean ; true and false if otherwise.

Given two integers as user inputs that represent the number of drinks to buy and the number of bottles to restock, create a Vend

ivann1987 [24]

Answer:

In C++:

#include <iostream>

using namespace std;

class VendingMachine {

public:

int initial = 20;};

int main() {

VendingMachine myMachine;

int purchase, restock;

cout<<"Purchase: "; cin>>purchase;

cout<<"Restock: "; cin>>restock;

myMachine.initial-=(purchase-restock);

cout << "Inventory: "<<myMachine.initial<<" bottles";

return 0;}

Explanation:

This question is incomplete, as the original source file is not given; so, I write another from scratch.

This creates the VendingMachine class

class VendingMachine {

This represents the access specifier

public:

This initializes the inventory to 20

int initial = 20;};

The main begins here

int main() {

This creates the object of the VendingMachine class

VendingMachine myMachine;

This declares the purchase and the restock

int purchase, restock;

This gets input for purchase

cout<<"Purchase: "; cin>>purchase;

This gets input for restock

cout<<"Restock: "; cin>>restock;

This calculates the new inventory

myMachine.initial-=(purchase-restock);

This prints the new inventory

cout << "Inventory: "<<myMachine.initial<<" bottles";

return 0;}
