Read three integers from user input without a prompt. Then, print the product of those integers. Ex: If input is 2 3 5, output is 30. Note: Our system will run your program several times, automatically providing different input values each time, to ensure your program works for any input values. See How to Use zyBooks for info on how our automated program grader works.
Answer:
Explanation:
The following code is written in Java and simply grabs the three inputs and saves them into three separate variables. Then it multiplies those variables together and saves the product in a variable called product. Finally, printing out the value of product to the screen.
import java.util.Scanner;
public class Main{
public static void main(String[] args){
Scanner in = new Scanner(System.in);
int num1 = in.nextInt();
int num2 = in.nextInt();
int num3 = in.nextInt();
int product = num1 * num2 * num3;
System.out.println(product);

Read Chapter 2 in your text before attempting this project. An employee is paid at a rate of $16.78 per hour for the first 40 hours worked in a week. Any hours over that are paid at the overtime rate of one-and-one-half times that. From the worker's gross pay, 6% is withheld for Social Security tax, 14% is withheld for federal income tax, 5% is withheld for state income tax and $10 per week is withheld for union dues. If the worker has three or more dependents, then an additional $35 is withheld to cover the extra cost of health insurance beyond what the employer pays. Write a program that will read in the number of hours worked in a week and the number of dependents as input and will then output the worker's gross pay, each withholding amount, and the net take-home pay for the week.

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

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).

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.

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.

If you are writing an algorithm and you aren’t confident that you understand the problem, what can you do?
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.
let m be a positive integer with n bit binary representation an-1 an-2 ... a1a0 with an-1=1 what are the smallest and largest values that m could have
Answer:
Explanation:
From the given information:
[tex]a_{n-1} , a_{n-2}...a_o[/tex] in binary is:
[tex]a_{n-1}\times 2^{n-1} + a_{n-2}}\times 2^{n-2}+ ...+a_o[/tex]
So, the largest number posses all [tex]a_{n-1} , a_{n-2}...a_o[/tex] nonzero, however, the smallest number has [tex]a_{n-2} , a_{n-3}...a_o[/tex] all zero.
∴
The largest = 11111. . .1 in n times and the smallest = 1000. . .0 in n -1 times
i.e.
[tex](11111111...1)_2 = ( 1 \times 2^{n-1} + 1\times 2^{n-2} + ... + 1 )_{10}[/tex]
[tex]= \dfrac{1(2^n-1)}{2-1}[/tex]
[tex]\mathbf{=2^n -1}[/tex]
[tex](1000...0)_2 = (1 \times 2^{n-1} + 0 \times 2^{n-2} + 0 \times 2^{n-3} + ... + 0)_{10}[/tex]
[tex]\mathbf {= 2 ^{n-1}}[/tex]
Hence, the smallest value is [tex]\mathbf{2^{n-1}}[/tex] and the largest value is [tex]\mathbf{2^{n}-1}[/tex]

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.
