Write a Java program that creates a two-dimensional array of type integer of size x by y (x and y must be entered by the user). The program must fill the array with random numbers from 1 to 9. Then, the program must print the original array and the elements that are in even columns of the array.
Answer:
The java program is as follows:
import java.util.*;
public class Main{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
Random r = new Random();
int x, y;
x = input.nextInt();
y = input.nextInt();
int[][] Array2D = new int[x][y];
for(int i = 0; i < x ; i++){
for(int j = 0; j < y; j++){ Array2D[i][j] = r.nextInt(9) + 1; }
}
for(int i = 0; i < x ; i++){
for(int j = 0; j < y; j++){ System.out.print(Array2D[i][j]+" "); }
System.out.println();
}
for(int i = 0; i < x ; i++){
for(int j = 1; j < y; j+=2){ System.out.print(Array2D[i][j]+" "); }
System.out.println();
}
}
}
Explanation:
This creates a random object
Random r = new Random();
This declares x and y as integers
int x, y;
This gets input for x
x = input.nextInt();
This gets input for y
y = input.nextInt();
This declares the 2D array
int[][] Array2D = new int[x][y];
The following iteration populates the array with integers 1 to 9
for(int i = 0; i < x ; i++){
for(int j = 0; j < y; j++){ Array2D[i][j] = r.nextInt(9) + 1; }
}
The following iteration prints all elements of the array
for(int i = 0; i < x ; i++){
for(int j = 0; j < y; j++){ System.out.print(Array2D[i][j]+" "); }
System.out.println();
}
The following iteration prints all elements on the even column
for(int i = 0; i < x ; i++){
for(int j = 1; j < y; j+=2){ System.out.print(Array2D[i][j]+" "); }
System.out.println();
}
What are the consequences of writing selection structures to include an unnecessary nested selection structure ?
Answer: less efficient code
Explanation:
When a programmer studies the specifications of a problem, then the programmer can then decide if the solution to the problem will require a nested selection structure or not.
One consequences of writing selection structures to include an unnecessary nested selection structure is that it produces a less efficient code.

In the U.S. fuel efficiency of cars is specified in miles per gallon (mpg). In Europe it is often expressed in liters per 100 km. Write a MATLAB user- defined function that converts fuel efficiency from mpg to liters per 100 km. For the function name and arguments, use Lkm-mpgToLpkm (mpg). The input argument mpg is the efficiency in mi/gl, and the output argument Lkm is the efficiency in liters per 100 km (rounded to the nearest hundredth). Use the function in the Command Window to:________.
(a) Determine the fuel eficiency in liters per 100 km of a car whose fuel effi- ciency is 21 mi/gal.
(b) Determine the fuel efficiency in liters per 100 km of a car whose fuel effi- ciency is 36 mi/gal.
Answer and Explanation:
Using MATLAB code:
Function Lkm = Lkm-mpgToLpkm (mpg)
Lkm= mpg*1.60934/3.78541;
Lkm= Lkm^(-1);
Lkm= Lkm*100;
%the code above defines a function Lkm and takes argument/input to its parameter mpg(miles per gallon) and then returns/output Lkm which is the litres per kilometers conversion from miles per gallon input.
end
To call the function written above with argument 30 mpg, we write:
Lkm= Lkm-mpgToLpkm (30)
The following pseudocode describes how a widget company computes the price of an order from the total price and the number of the widgets that were ordered. Read the number of widgets. Multiple the number of widgets by the price per widget of 9.99. Compute the tax (5.5 percent of the total price). Compute the shipping charge (.40 per widget). The price of the order is the sum of the total widget price, the tax, and the shipping charge. Print the price of the order
Answer:
The program in Python is as follows:
widget = int(input("Widgets: "))
price = widget * 9.9
tax = price * 0.55
ship = price * 0.40
totalprice = price + tax + ship
print("Total Price: $",totalprice)
Explanation:
The question is incomplete, as what is required is not stated.
However, I will write convert the pseudocode to a programming language (in Python)
Get the number of widgets
widget = int(input("Widgets: "))
Calculate price
price = widget * 9.9
Calculate the tax
tax = price * 0.55
Calculate the shipping price
ship = price * 0.40
Calculate the total price
totalprice = price + tax + ship
Print the calculated total price
print("Total Price: $",totalprice)

The first step of learning about spreadsheets is understanding the terminology you will encounter as you work through this lesson. The glossary below lists terms that are specific to spreadsheet applications. Terminology that we learned when we looked at wordprocessing (such as copy, paste, clipboard, etc.) also apply to spreadsheet applications.
Design a class named Employee. The class should keep the following information in member variables:
Employee name
Employee number
Hire Date
Write one or more constructors and the appropriate accessor and mutator functions for the class.
Next, write a class named ProductionWorker that is derived from the Employee class. The ProductionWorker class should have member variables to hold the following information:
Shift (an integer)
Hourly pay rate (a double)
The workday is divided into two shifts: day and night. The shift variable will hold an integer value representing the shift that the employee works. The day shift is shift 1 and the night shift is shift 2. Write one or more constructors and the appropriate accessor and mutator functions for the class. Demonstrate the classes by writing a program that uses a ProductionWorker object."

The compound known as butylated hydroxytoluene, abbreviated as BHT, contains carbon, hydrogen, and oxygen. A 1.501 g sample of BHT was combusted in an oxygen rich environment to produce 4.497 g of CO2(g) and 1.473 g of H2O(g). Insert subscripts below to appropriately display the empirical formula of BHT.
Answer:
C15H24O
Explanation:
n(C) = 4.497 g/44g/mol = 0.1022
Mass of C = 0.1022 × 12 = 1.226 g
n(H) = 1.473g/18 g/mol = 0.0823 ×2 moles = 0.165 moles
Mass of H = 0.0823 × 2 ×1 = 0.165g
Mass of O= 1.501 -(1.226 + 0.165)
Mass of O= 0.11 g
Number of moles of O = 0.11g/16g/mol = 0.0069 moles
Dividing through by the lowest ratio;
0.1022/0.0069, 0.165/0.0069, 0.0069/0.0069

You are a high school student learning about computers and how to build them. As a class project, you have built a new computer. You power on your computer and begin to configure the system. After a short while, you notice smoke coming from the PC, and shortly after that, the computer stops working. After removing the computer case, you see that the CPU and surrounding areas are burnt and very hot. You realize that the costly mistake you made was not using a heat sink. When rebuilding your computer, which cooling systems would MOST efficiently remove heat from the CPU?
Answer:
You can use thermal paste, active heat sink, liquid pipes, and even a fan. These are just some that I've heard.
Explanation:
All of these are cooling and will stop the Central Processing Unit from overheating.
Hope this helps :)
When rebuilding your computer, the cooling systems which would most efficiently remove heat from the Central processing unit (CPU) are: cooling fan and thermal compounds.
A computer refers to an intelligent electronic device that is designed and developed to receive raw data as an input and then processes these data into an information (output) that is usable by an end user.
Basically, the main part of a computer are broadly divided into the following;
Input devices (peripherals). Output devices (peripherals). Motherboard. Memory and storage device.Central processing unit (CPU).A cooling device can be defined as a device that is designed and developed to efficiently remove or dissipate heat from the inside of a computer. The cooing system used in a computer are grouped into two
(2) main categories and these are:
I. Active cooling device: an example is a cooling fan.
II. Passive cooling device: an example is a heat sink.
In conclusion, the cooling systems which would most efficiently remove heat from the Central processing unit (CPU) are cooling fan and thermal compounds.

Christina has been asked by the firewall administration group to identify secure network protocols that can be used to prevent network analyzers from being able to read data in flight. What are considered as secure network protocols?
Answer:
SSH, HTTPS and SMTP
Explanation:
Data theft can be defined as a cyber attack which typically involves an unauthorized access to a user's data with the sole intention to use for fraudulent purposes or illegal operations. There are several methods used by cyber criminals or hackers to obtain user data and these includes DDOS attack, SQL injection, man in the middle, phishing, etc.
Encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext. Once, an information or data has been encrypted it can only be accessed and deciphered by an authorized user.
Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.
Hence, SSH, HTTPS and SMTP are considered as secure network protocols.
HTTPS is acronym for Hypertext Transfer Protocol Secure while SSL is acronym for Secure Sockets Layer (SSL).
SMTP is an acronym for Simple Mail Transfer Protocol and it uses the standard port number of 25 to provide clients with requested services.

Answer:
The function is as follows:
def number_of_pennies(dollars,pennies=0):
return dollars*100+pennies
Explanation:
This defines the function
def number_of_pennies(dollars,pennies=0):
This returns the number of pennies
return dollars*100+pennies
Note that, if the number of pennies is not passed to the function, the function takes it as 0
Answer:
Code is given as:-
#number_of_pennies function with one default argument with pennies as 0 when no pennies parameter is given
def number_of_pennies(dollars,pennies = 0):
pennies = dollars*100 + pennies #one dollar equals 100 pennies so calculate total pennies with this formula
return pennies #return total pennies
print(number_of_pennies(int(input()),int(input()))) #both Dollars and pennies
print(number_of_pennies(int(input()))) #Dollars only

Heinrich Koch is a second-year college student. Last semester his best friend had his laptop stolen. The laptop was an old computer that he planned to replace soon, but the greatest loss was his data: he had not performed a backup and all his data was lost. Heinrich himself does not perform data backups but knows that he needs to do that on a regular basis. He has decided to use an online backup service that will automatically back up his data whenever it changes. Evaluate and compare reviews of online backup services. Consider iDrive, Carbonite, Acronis True Image, BackBlaze, and others you might find in your research. Recommend a service that you consider the best solution for Heinrich. Discuss your reviews and mention speed, security, and features in your recommendation.
Answer:
Acronis True Image is the one I would recommend out of these mentioned online backup services.
Explanation:
The evaluations and reviews of each of the online backup services are as follows:
a. iDrive
For this, we have:
Speed = 60% - fair
Security = 100% - excellent
Privacy = 88% - very good
Features = 95% - excellent
Pricing = 85% - Very good
Because of its various features, pricing, and usability, IDrive reviews suggest that it is a very efficient online backup solution. However, there have been complaints concerning its speed and the fact that there are no monthly plans available.
b. Carbonite
For this, we have:
Speed = 60% - fair
Security = 100% - excellent
Privacy = 87% - very good
Pricing = 85% - very good
File backup and restoration = 75% - good
Carbonite reviews reveal that it is simple to use and provides limitless backup for one device. The main drawback is that it has extremely poor backup speeds.
c. Acronis True Image
This is fast, simple and intuitive
It has complete control over the backup updates, including how and when they occur.
It is not expensive.
Acrnonis True image is a powerful backup storage service. It enables data and file backup and restoration from USB drives.
Many reviewers of Acrnonis True image have stated that they have had no issues with its service, that it is worth purchasing, and that there are no concerns.
d. Backblaze
For this, we have:
Speed = 75% - good
Security = 75% - good
Privacy = 70% - decent
Pricing = 100% - excellent
Support = 95% - excellent
Features = 65% - decent
File back-up and restoration = 70% - decent
Backblaze is one of the most popular internet backup services. This storage service, however, does not allow for ustomization.
Recommendation
Acronis True Image is the one I would recommend out of these mentioned online backup services. This is due to the fact that it delivers a large amount of accurate and high-quality data storage. It is quick, simple and intuitive, which is what most people care about. Furthermore, reviewers have stated that this service is quite effective and that there have been very few issues with it. The other services demonstrate that their services have flaws, such as lack of customization and slowness.
