Answer:
(b) int **arr = new int*[10];
Explanation:
An <em>array of pointers</em> is simply an array containing pointer variables. These pointer variables may be Strings, integers, doubles e.t.c
To declare such arrays of pointers, for example, of integers, in C++, we write;
int **arr = new int*[10];
The left hand side of the above code snippet i.e int ** arr, suggests that arr is a pointer that points to a pointer to integer variables.
The right hand side i.e new int* [10], creates a new array of 10 integer pointer variables.
Now, put together, int **arr = new int*[10] will create/declare an array of pointers of integers having a size of 10.
Answer:
The correct answer to the following question will be Option C (h(h(h(h(po))))).
Explanation:
As we recognize, the individual and device generate a linearly modified password that used a hash feature at the Lamport one-time code or password.
hn(x) = h(hn-1(x)) hn-1(x) = h(hn-2(x)) ........ h2(x) = h(h(x)) h1x = h(x)
Suppose that Bob and Alice accept an initial P0 password as well as a counter 6.
The counter would be 6-1 that is 5 throughout the next step, as well as the password should be h5(P0). Which implies the third code created over the next step would be h4(P0).
So, Option C is the right answer.
In object-oriented programming, the object consist of both the data and the functions that operate on the data. In object-oriented programming, a data member plays the role of neither A nor B.
- Objects are the product of abstract data types that has inside of it both data and function altogether.
A data member often has different classes. They can be private or public.
Object-oriented programming (OOP) is simply known as a computer programming model that put together software design around data, or objects.

<u>The Virus:</u>
A virus can be defined as a malicious program, that breaks into the computer without the consent of the user and sometimes even without the knowledge of the user. Viruses are also of different types and categories.
There are certain kinds of malware and spyware that enter a computer and start encrypting the user's data. Generally, a user gets to know about the existence of a virus when the computer programs begin to misbehave. Some files get corrupted and the user can't access them anymore.
Some files and programs may also get deleted as if they weren't even present on the system. But in case someone has installed good anti-virus software, they will get a notification as soon as some file containing some kind of virus enters the computer.
