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.
I believe that is true
Hope this helps!! :)

Answer:
The benefits of SSDs over HDDs include:
Faster read/write speeds. SSDs can access large files quickly.
Quicker boot times and better performance. Because the drive does not need to spin up as an HDD would, it is more responsive and provides better load performance.
Durability. ...
Power consumption. ...
Quieter. ...
Size.
Explanation:
convection requires a medium is not the main difference, it is simply the most obvious aspect of what is a fundamentally different mechanism for transfering energy. Convection is the transfer of energy by movement of a medium, whereas radiation is the transfer of energy by, well, thermal radiation. Conduction also requires a medium, but, again, it is a fundamentally different mechanism than either convection or radiation; in this case it is the transfer of energy through a medium.
Unfortunately, analogies are hard but if you can visualize the particles involved, it would help. Picture the red hot iron you mentioned. On a molecular level, the material is emitting lots and lots of photons (hence why it is glowing red). The creation of these photons takes energy; energy from the heat of the iron. These photons leave the iron, pass through the environment, and eventually collide with some other object where they are absorbed and deposit their energy. This is radiative heat transfer. If that energy is deposited on your retina or a CCD (like in a digital camera), an image forms over time. This is how infrared goggles work and they would work equally well in high vacuum as here on earth.
In conduction, the next simplest example, there is no generation of photons (physics nerds forgive me for the sake of simplicity). The individual atoms in the object are vibrating with heat energy. As each atom gains energy from it's more energetic neighbors, so it gives up energy to its less energetic ones. Over time, the heat "travels" through the object.
In convection, the molecules of gas near the object gain energy, like in the conduction case, but those same molecules that gained energy then travel through the environment to some other location where they then give off their heat energy.
In summary:
radiation = generated and absorbed photonsconduction = molecules exciting their neighbors succesivelyconvection = molecules heated like in conduction, but then move to another location
