What is computer programming?

Computer programming is defined as the process of carrying out a specific computation, typically through creating an executable computer program. Computer programmers create code and scripts, modify them, and test them to make sure that software and applications function as intended. They convert the blueprints made by engineers and software developers into computer-readable instructions.

The algorithm determines whether the key the number you're looking for and the array's middle value are equal. If so, the key is in the middle and the search is complete. The program then determines if the key is larger or less than the middle value if it isn't.

Thus, PRE: True POST: is Sorted(a) An > 1 C) PRE : n > 1A is Sorted (a). 10 sxs a[n-1] POST: result == x E a vissorted (a).

Write a program that plays the popular scissor-rockpaper game. (A scissor can cut a paper, a rock can knock a scissor, and a paper can wrap a rock.) The program randomly generates a number 0, 1, or 2 representing scissor, rock, and paper. The program prompts the user to enter a number 0, 1, or 2 and displays a message indicating whether the user or the computer wins, loses, or draws. Here are sample runs:

scissor (0), rock (1), paper (2): 1
The computer is scissor. You are rock. You won
scissor (0), rock (1), paper (2): 2
The computer is paper. You are paper too. It is a draw

Answers

Answer:

import random

computer = random.randint(0, 2)

user = int(input("scissor (0), rock (1), paper (2): "))

if computer == 0:

   if user == 0:

       print("The computer is scissor. You are scissor too. It is a draw")

   elif user == 1:

       print("The computer is scissor. You are rock. You won")

   elif user == 2:

       print("The computer is scissor. You are paper. Computer won")

elif computer == 1:

   if user == 0:

       print("The computer is rock. You are scissor. Computer won")

   elif user == 1:

       print("The computer is rock. You are rock too. It is a draw")

   elif user == 2:

       print("The computer is rock. You are paper. You won")

elif computer == 2:

   if user == 0:

       print("The computer is paper. You are scissor. You won")

   elif user == 1:

       print("The computer is paper. You are rock. Computer won")

   elif user == 2:

       print("The computer is paper. You are paper too. It is a draw")

Explanation:

*The code is in Python.

Import the random to be able to generate number number

Generate a random number between 0 and 2 (inclusive) using randint() method and set it to the computer variable

Ask the user to enter a number and set it to the user variable

Check the value of computer the computer variable:

If it is 0, check the value of user variable. If user is 0, it is a draw. If user is 1, user wins. If user is 2, computer wins

If it is 1, check the value of user variable. If user is 0, computer wins. If user is 1, it is a draw. If user is 2, user wins

Do you think it is acceptable to copy and paste material from a web page into a term paper?​

Answers

Answer:

Possibly, if it is a small quote from a factual and reliable site which properly cited, allowed, and being used to prove an idea or as support for a claim. You can also paraphase. However, if it is a large piece of material in which no effort is needed for the person submitting the paper, then no. Copy and paste is generally only saved for quoting something direct, such as results from scientific reasearch. You really need to be careful not to plagarise; so, for a term paper, it may be a better idea to stay clear of copy and paste if you are unsure.

Assume that you are able to do an exhaustive search for the key to an encrypted message at the rate of 100 Million trials per second. (a) (7 Points) How long in (days or years) would it take for you to find the key on the average to a code that used 112-bit key on average

Answers

Answer:

8.22 × 10²⁰ years

Explanation:

Given that:

Total frequency = 100 million per record

The length of the key used for the encryption = 112 bit key

To calculate the number of seconds in  a year, we have:

= 365 × 24 × 60 × 60

= 3.1536 × 10⁷ seconds

Thus, on average, the number of possible keys that is required to check for the decryption should be at least  2¹¹¹ keys.

[tex]\mathbf{ = \dfrac{2^{111} \times 10^6}{3.1536 \times 10^7} = 8.22 \times 10^{20} \ years}[/tex]

Thus, it will take a total time of about 8.22 × 10²⁰ years on average.

Create the logic for a program that prompts a user for 12 numbers and stores them in an array. Pass the array to a method that reverses the order of the numbers. Display the reversed numbers in the main program.

Answers

Answer:

Explanation:

The following program is written in Python. It first creates a method that reverses the array using the built in reverse function. Then it creates the array, creates a loop to ask the user to enter 12 numbers while passing each input into the array. Finally, it passes that array into the previously created reverse method and prints out the new array.

def reverse(num_arr):

   num_arr.reverse()

Consider the following class definition.
public class Tester
{

private int num2;
/missing constructor /
}
The following statement appears in a method in a class other than Tester. It is intended t o create a new Tester object t with its attributes set to 10 and 20.
Tester t = new Tester(10,20);

Which can be used to replace / missing constructor / so that the object t is correctly created?

Answers

Answer:

Explanation:

The following constructor needs to be added to the code so that the object called t can be created correctly...

public Tester(int arg1, int arg2) {

    num1 = arg1;

    num2 = arg2;

}

This basic constructor will allow the object to be created correctly and will take the two arguments passed to the object and apply them to the private int variables in the class. The question does not state what exactly the Tester constructor is supposed to accomplish so this is the basic format of what it needs to do for the object to be created correctly.

Which of the following best describes the existence of undecidable problems?

Answers

Answer:

D.

Explanation:

Its the exact definition of an undecidable problem. Plus I have my notebook open next to me and that's what it says, trust bro.

An undecidable problem is a problem for which no algorithm can be constructed that always produces a correct output. The correct option is D.

What is undecidable problem?

Problems that cannot be solved by an algorithm are known as undecidable problems since no computer program can come up with a solution that works for every scenario.

This is a key drawback of computing systems, and it has been analytically shown that some issues are intractable from the start.

Decision issues that lack an algorithmic solution are referred to as undecidable.

A issue that cannot be solved by a computer or computer software of any type has never been solved by a computer. There is no such thing as a Turing machine that can solve an insoluble problem.

Thus, the correct option is D.

If you are writing an algorithm and you aren’t confident that you understand the problem, what can you do?

Answers

Answer:

divide it into smaller pieces

Explanation:

Usually, the main reason a programmer does not understand a problem fully is that there is too much information. The best way to try and fully understand a problem is to divide it into smaller pieces. Start off by answering the question what is the expected output for an input. Then divide each individual issue within the problem. This will allow you as a programmer/developer to create an individual solution for each individual issue within the problem and then test to make sure that the input gives the correct output.

The SANS Top 20 Critical Security Controls For Effective Cyber Defense

Explanation:

Password/PIN Policy

Developing a password and personal identification number policy helps ensure employees are creating their login or access credentials in a secure manner. Common guidance is to not use birthdays, names, or other information that is easily attainable.

Device Controls

Proper methods of access to computers, tablets, and smartphones should be established to control access to information. Methods can include access card readers, passwords, and PINs.

Devices should be locked when the user steps away. Access cards should be removed, and passwords and PINs should not be written down or stored where they might be accessed.

Assess whether employees should be allowed to bring and access their own devices in the workplace or during business hours. Personal devices have the potential to distract employees from their duties, as well as create accidental breaches of information security.

As you design policies for personal device use, take employee welfare into consideration. Families and loved ones need contact with employees if there is a situation at home that requires their attention. This may mean providing a way for families to get messages to their loved ones.

Procedures for reporting loss and damage of business-related devices should be developed. You may want to include investigation methods to determine fault and the extent of information loss.

Internet/Web Usage

Internet access in the workplace should be restricted to business needs only. Not only does personal web use tie up resources, but it also introduces the risks of viruses and can give hackers access to information.

Email should be conducted through business email servers and clients only unless your business is built around a model that doesn't allow for it.

Many scams and attempts to infiltrate businesses are initiated through email. Guidance for dealing with links, apparent phishing attempts, or emails from unknown sources is recommended.

Develop agreements with employees that will minimize the risk of workplace information exposure through social media or other personal networking sites, unless it is business-related.

Encryption and Physical Security

You may want to develop encryption procedures for your information. If your business has information such as client credit card numbers stored in a database, encrypting the files adds an extra measure of protection.

Key and key card control procedures such as key issue logs or separate keys for different areas can help control access to information storage areas.

If identification is needed, develop a method of issuing, logging, displaying, and periodically inspecting identification.

Establish a visitor procedure. Visitor check-in, access badges, and logs will keep unnecessary visitations in check.

Security Policy Reporting Requirements

Employees need to understand what they need to report, how they need to report it, and who to report it to. Clear instructions should be published. Training should be implemented into the policy and be conducted to ensure all employees understand reporting procedures.

Empower Your Team

One key to creating effective policies is to make sure that the policies are clear, easy to comply with, and realistic. Policies that are overly complicated or controlling will encourage people to bypass the system. If you communicate the need for information security and empower your employees to act if they discover a security issue, you will develop a secure environment where information is safe.

A perpetual system of inventory can be defined as a method of financial accounting, which involves the updating informations about an inventory on a continuous basis (in real-time) as the sales or purchases are being made by the customers, through the use of enterprise management software applications and a digitized point-of-sale (POS) equipment.

Under a perpetual system of inventory, updates of the journal entry for cost of goods sold or received would include debiting accounts receivable and crediting sales immediately as it is being made or happening.

Hence, an advantage of the perpetual system of inventory over the periodic system of inventory is that, it ensures the inventory account balance is always accurate provided there are no spoilage, theft etc.

The following are the characteristic of a perpetual inventory system;

I. It is the most popular choice for modern business.

II. Inventory is updated in near real-time.

III. It provides up-to-date balance information and requires fewer physical counts.

Your output should be very well organized, and use the correct formatting. (Including precision)

Answers

Answer:

In Python:

order = int(input("Order: "))

discount = 0

if(order >= 10 and order <20):

    discount = 0.20

elif(order >= 20 and order <50):

    discount = 0.30

elif(order >= 50 and order <100):

    discount = 0.35

elif(order >= 100):

    discount = 0.40

price = order * 4.1

discount = discount * price

print("With your order of "+str(order)+" items, the total value will be $"+str(round(price,2))+" with a discount of $"+str(round(discount,2))+" for a final price of $"+str(round((price-discount),2)))

Explanation:

This prompts the user for number of orders

order = int(input("Order: "))

This initializes the discount to 0

discount = 0

For orders between 10 and 19 (inclusive)

if(order >= 10 and order <20):

-----------discount is 20%

    discount = 0.20

For orders between 20 and 49 (inclusive)

elif(order >= 20 and order <50):

-----------discount is 30%

    discount = 0.30

For orders between 50 and 99 (inclusive)

elif(order >= 50 and order <100):

-----------discount is 35%

    discount = 0.35

For orders greater than 99

elif(order >= 100):

-----------discount is 40%

    discount = 0.40

This calculates the total price

price = order * 4.1

This calculates the pre discount

discount = discount * price

This prints the report

print("With your order of "+str(order)+" items, the total value will be $"+str(round(price,2))+" with a discount of $"+str(round(discount,2))+" for a final price of $"+str(round((price-discount),2)))
