Answer:
NTFS
Explanation:
NTFS (New Technology Files System) is the newer drive format. Microsoft introduced NTFS in 1993, as a component of the corporate-oriented Windows NT 3.1 and then Windows 2000. It became common in consumer computers in Windows 7 and 8 defaulting to NTFS format on new PCs.
The option that declares an abstract method in an abstract Java class is option(B.) public abstract void method().
<h3>In Java, are abstract methods compatible with abstract classes?</h3>
Class and method abstraction is when Objects cannot be created using the abstract class, which is a restricted class. In addition to not having a body, an abstract method is only applicable to abstract classes. Subclasses provide the body.
Hence, consists of only the method definition and not any implementation. An Abstract Method is a method that doesn't have a body. A class that is abstract must declare it. Due to the need for the abstract class to implement each abstract method, the abstract method can never be considered final.

Answer:
A complex data type can be created by the use of class or structures.
#include <iostream>
using namespace std;
class complex{//creating a class complex to store a complex value.
public://defining all the values public.
int real;
int img;
complex(int real,int img)//parameterized constructor.
{
this->real=real;
this->img=img;
}
};
int main() {
complex n1(1,2);//n1 is a complex number with real part 1 and imaginary part 2.
cout<<n1.real<<" i"<<n1.img<<endl;
return 0;
}
Output
1 i2
Explanation:
I have created a class complex to store complex number with two integer parts real and imaginary.You can also declare them float if you wan to store decimal values and after that i have created a parameterized constructor with real and imaginary values.So we can assign the values at the time of declaration of the object of class complex.
2.) Roman engineers lightened the dome as much as possible; not only its thickness progressively decreases, but the materials used in the upper part of the dome were lighter with internal spaces within the dome walls. The decrease in thickness has the effect that while the interior of the ceiling is spherical, its exterior is slightly “flattened”.
