1) You have a class called Sheep that wants to keep track of how many Sheep have ever been created. Where is a good place to put that variable? 2) When an h file mentions another class, what is that called? (When a cpp file needs to use a class, they include it. This is an h file just mentioning a class, like it has a pointer of that type. You are promising the compiler that the class is in another file.) 3) What is a good guideline for deciding you must write a copy constructor, an assignment operator, and a destructor? 4) void Rock::Func( const Rock & X){} What is that argument type called and what does it do? 5) We saw overloading the = sign. How do you declare a class wanting to override the parenthesis operator?

Answers

Answer 1

Answer:

The counter variable for the sheep count should be declared and initialized before the constructor in the class. The extern keyword should be used to declare the class in the receiving C source file. A constructor is defined when there is a need to instantiate an object with an argument and an assignment operator is used to initialize a variable. The const keyword is used to specify a variable whose value should not change during the course of the program execution.

Explanation:

The C programming language is an object-oriented programming language and has variable specifiers to define variable scopes in a program.

Which of the following is used to encrypt web application data?
a. MD5
b. AES
c. SHA
d. DHA

Answers

Answer:

b. AES

Explanation:

AES is an acronym for Advanced Encryption Standard and it is a cryptographic or symmetric block cipher that is based on a substitution-permutation network (SPN) used for the encryption of sensitive data over the internet or web. AES uses a key length of 128, 192 or 256 bits and a block length of 128 bits to encrypt data on web applications.

It is an encryption standard of the government of the United States of America and is supported by the National Institute of Standards and Technology (NIST).

Hence, AES is used to encrypt web application data and it uses an algorithm developed by Vincent Rijmen and Joan Daemen, known as the Rijndael algorithm.

Write code that determines the number of full days represented by the number of hours stored in the variable hours and stores that value in the variable full_days. For example, the number of full days in 50 hours is 2. Ignore any leftover hours that don't contribute to a full day. Assume the value of hours has already been initialized. Solve It!

Answers

Answer:

hours = 50

full_days = int(hours / 24)

print("The number of full days in " + str(hours) + " hours is " + str(full_days))

Explanation:

Initialize the hours

Since there are 24 hours in a full day, divide the hours by 24. Note that you need to typecast it to the int, because the result is a decimal value by default

Explain demand paging with a proper example

Answers

Demand paging :

In computer operating systems, demand paging (as opposed to anticipatory paging) is a method of virtual memory management. In a system that uses demand paging, the operating system copies a disk page into physical memory only if an attempt is made to access it and that page is not already in memory (i.e., if a page fault occurs). It follows that a process begins execution with none of its pages in physical memory, and many page faults will occur until most of a process's working set of pages are located in physical memory. This is an example of a lazy loading technique.

How do I fix the error?

Answers

Answer:

num = int(input("Enter a number: "))

print(num * 8)

Explanation:

I highlighted the parts that are added

Since you are getting an input from the user, you need to set the result to a variable. In this case, it is num.

Since it is a number, you need to specify the its type. In this case, it may be int.

Also, the quotation marks must be written as seen.

The corrected program which ensures that the program runs correctly is written thus :

num = int(input("Enter a number: ")

#user supplied input should be assigned to the varibale num

print(num * 8)

#multiplies num by 8 and displays the output.

The num variable in the second line isn't attached to any value, therefore, it will throw an error.

The user input value should be attached to the variable, 'num'

The second line of code multiplies num by 8 and displays the product.

Therefore, if the the user input is 3 ; the final result displayed will be : (3 × 8) = 24.

print() essentially just calls up the native print dialog for a given window.

But as you're are thinking, it will work on any window or (i)frame.

thus if you write content to a frame, you can then call this to print it.

window.frameName.print();

note the only drawback (and its a big one), is that this calls up the print dialog... not the print preview window... thus the user doesn't really get a chance to see what they are printing and/or scale it to fit their printer/paper.

What is true about connectionless packet switched networks? a. each datagram must contain both source and destination addresses b. without a connection, datagrams may not arrive in sequential order at the destination c. establishment of a connection between communicating points is not required prior to exchanging datagrams, thus reducing overhead communications d. all of the above are true

Answers

Answer:

d. all of the above are true

Explanation:

Connectionless Packet Switching is a term that is used in computer networking operations to describe the breaking of information exchange path into a various packet of small sizes acquired and refined over network switches and routers, which is then transferred from one subsequent node to the other. It is sometimes referred to as Datagram Networks

However, during this operation, Connectionless Packet Switching must satisfy the following amongst others:

1.  each datagram must comprise both source and destination addresses

2.   without a connection, datagrams may not come in sequential order at the destination

3.  establishment of a connection between communicating points is not needed prior to exchanging datagrams, thus reducing overhead communications

Therefore, considering the available options, the correct answer is option D

Explanation:

In this scenario, your network administrator finds a virus in the network software. Fortunately, she was able to eliminate it before it resulted in a denial-of-service attack, which would have prevented legitimate users of the networked database from gaining access to the records needed. It turns out that the network software did not have adequate security protections in place. The fact that this virus was successfully inserted into the network software points to a vulnerability of the network software.

In Cybersecurity, vulnerability can be defined as any weakness, flaw or defect found in a software application or network and are exploitable by an attacker or hacker to gain an unauthorized access or privileges to sensitive data in a computer system.

This ultimately implies that, vulnerability in a network avail attackers or any threat agent the opportunity to leverage on the flaws, errors, weaknesses or defects found in order to compromise the security of the network.

Some of the ways to prevent vulnerability in a network are;

1. Ensure you use a very strong password with complexity through the use of alphanumerics.

2. You should use a two-way authentication service.

3. You should use encrypting software applications or services.
