Answer:
The answer is option d.
Explanation:
The 'querySelectorAll' function enables you to extract the list of items that fit the CSS selector you choose. It's just a way to find JavaScript components. It is very adaptable and enables you to search for tags, classes, IDs, combinations of parent/child, attributes, etc.
In other words, we can say that the querySelectorAll() method returns all the matches. and other options are not correct that can be described as follows:
In option a and b, the object is a collection of unordered properties, that can be changed in adding, deleting and read-only. The option a is an attribute, that is used in CSS and option b is used in JavaScript for the property name. In option c, It reverts the element with the fixed value, that has the ID attribute.Define the following Window class: - integer data members, width and height - a constructor that accepts two integer parameters (width followed by height) and uses them to initialize the data members - a friend function, areSameSize, that accepts two Window objects and returns a boolean indicating if they are the same size. Two windows are the same size if the widths and heights match.
Answer:
The code to this question can be given as:
Code:
class Window // define class window.
{
private:
int width, height; //define global variable
public:
Window(int w,int h) //define parameterized constructor.
{
width = w; //holds parameter value.
height = h; //holds parameter value.
}
friend bool areSameSize(Window a, Window b) //define friend function.
{
if ((a.height == b.height) && (a.width == b.width)) //conditional statement.
{
return true; //return value true.
}
else //else block
{
return false; //return value false.
}
}
};
Explanation:
In the above code we define a class that is "Window". In this class we define private variable that is "width and height". In this class, we define a parameterized constructor and pass two integer variable that is "w and h". The w variable stands for width and h variable is stands for height. In this constructor, we use a global variable that holds constructor parameter value.In this class, we define friend function. This function is used to provide accessibility to private data members and member function outside the class. The return type of this function is bool because it will give true or false value. In this function, we use the conditional statement. In the if block we check a.height value is equal to b.height and a.width value is b.width. if it is true it will return true else it will return false.
Write the definitions for three function named max. Each receives two parameters, of the same type, and returns the larger of the two values. Define one of these functions to apply to type double, another to type int and a third to type char.
Answer:
The method definition to this question can be given as:
Method definition:
double max(double x, double y) //define method with double parameter
{
if (x>=y) //check condition.
return x; //return value
else
return y; //return value
}
double max(int x, int y) //define method with integer parameter
{
if (x>=y) //check condition
return x; //return value
else
return y; //return value
}
double max(char x, char y) //define method with char parameter
{
if (x>=y) //check condition
return x; //return value
else
return y; //return value
}
Explanation:
The above method definition can be described as below:
In the first method definition first, we define a method that is "max()". In this method we pass two variables as a parameter that is "x and y" and the datatype of this is double. Then we use a conditional statement. In the if block we check if variable x is greater then equal to y then it will return x else it will return y. In the second method definition, we define a method that is same as the first method name but in this method, we pass two integer variable that is "x and y". Then we use a conditional statement. In the if block we check if variable x is greater then equal to y then it will return x else it will return y. In the third method definition, we define a method that is same as the first and second method name but in this method, we pass two char variable that is "x and y". Then we use a conditional statement. In the if block we check if variable x is greater then equal to y then it will return x else it will return y.Hugo has created an HTML document to which he has attached an external CSS style sheet containing styles that define all HTML elements in the document.

Answer: Information content
Explanation:
You’re using Disk Manager to view primary and extended partitions on a suspect’s drive. The program reports the extended partition’s total size as larger than the sum of the sizes of logical partitions in this extended partition. What might you infer from this information?
a. The disk is corrupted.
b. There’s a hidden partition.
c. Nothing; this is what you’d expect to see.
d. The drive is formatted incorrectly
Answer:
b. There’s a hidden partition.
Explanation:
The hidden partition is a separate section set aside on OEM computer hard drives, often alluded to as the recovery partition and restore partition.
This portion of memory is used by the manufacturer to preserve the data used to restore your computer to its default settings.
This function is particularly useful as it does not involve the CD or DVD of the operating system.
If the extended partition's size is larger than the sum of its logical partitions reported by Disk Manager, it may indicate the presence of a hidden partition on the drive.
Explanation:If you are using Disk Manager to view primary and extended partitions on a suspect's drive and you observe that the extended partition's total size is reported as larger than the sum of the sizes of logical partitions within it, you might infer that there's a hidden partition. This observation suggests that some disk space within the extended partition is not accounted for by the visible logical partitions, potentially implying that there may be a partition or space that is not immediately apparent within the file system's structure. It is not uncommon for individuals with technical knowledge to hide partitions which can be used to store data one does not wish to be easily accessible.
Given an array of ints named x and an int variable named total that has already been declared, write some code that places the sum of all the elements of the array x into total. Declare any variables that you need.
To get the sum of all the elements in an array and store it in a variable, you can use a loop to iterate through each element and add it to the total.
Explanation:To place the sum of all the elements of the array x into the variable total, you can use a loop to iterate through each element of the array and add it to the total. Here is an example code:
int[] x = {1, 2, 3, 4, 5};In this example, the variable total is initialized to 0. The loop iterates through each element of the array x, adding the value of each element to the total. Finally, the total variable will contain the sum of all the elements in the array.

A bakery collects data on sales. Each sales record includes the date of the sale and some metadata about the items that were part of the sale. The data includes: the names of the items sold, the types of items sold, the number of each item sold, and the price of each item sold. Which of the following CANNOT be determined from the bakery's data set?A. The total income from sales the bakery received in the past month. B. Which customer most frequently purchases bread. C. The item bought in the highest quantity in the past week. D. Days when certain items sell the most.
Answer:
B. Which customer most frequently purchases bread.
Explanation:
As per the scenario, the data we are receiving from the sales record of the bakery is :
The date on which the items are sold
Each items name which are sold
The number of each item sold and
The price of each item sold
These data are required to estimate how much the company has earned the profit during a given period of time.
So from the above scenario, there is no data given about the customer i.e customer name, customer number, etc. So there is no chance to track the details of a customer purchase history.
Therefore, the most appropriate answer is option B
UESTION 2 Choose the most appropriate data structure with which to represent the following: the items on a person's driver's license. A. array B. record C. array of records D. hierarchical record E. either b or d above

Traffic find and payments, accident details and insurance details, passport information. to keep all this records hierarchical record methods is required.
Keeping all the as single records is not advisable. Person of license data to captured or enter should be categorized
Which line in the following program will cause a compiler error? 1 #include 2 using namespace std; 3 int main() 4 { 5 int number = 5; 6 if (number >= 0 && <= 100) 7 cout << "passed.\n"; 8 else 9 cout << "failed.\n"; 10 return 0; 11 }
Answer:
Line 1
Explanation:
Line one is not complete. It should have been #include <iostream> This line tells the compiler to use the input and output header file for this program, the iostream header file contains the functions necessary for output statements used in 7 and 8
Final answer:
The compiler error occurs on line 6 due to a missing variable 'number' in the second part of the conditional expression inside the if statement.
Explanation:
The line in the program that will cause a compiler error is line 6. The conditional expression within the if statement is incomplete. Instead, it should be if (number >= 0 && number <= 100), where number is compared to 0 and 100. Without repeating the variable number for the second comparison, the compiler doesn't know what to compare 100 with, leading to an error.
In C++, each condition within a logical expression needs to be fully specified, including the variable that is being compared. In addition, C++ commands or statements must end with a semicolon, and the use of preprocessor directives like #include is for inserting the contents of files, such as , which is necessary for using cout.
A return value of 0 typically indicates successful termination of the program to the operating system, and the using namespace std statement makes it so that we can use elements of the std namespace without the prefix std::.
"Your supervisor has asked you to modify the AMOUNT column in the ORDERS table. He wants the column to be configured to accept a default value of 250. The table contains data that you need to keep. Which statement should you issue to accomplish this task?"
Answer:
ALTER TABLE orders
MODIFY (amount DEFAULT 250)
Explanation:
ALTER TABLE statement is used to modify "amount" column in the existing "orders" table MODIFY (amount DEFAULT 250) is used to set the default value 250 of the "amount" column.Therefore if the supervisor wants the amount column to be configured to accept a default value of 250, then "ALTER TABLE orders MODIFY (amount DEFAULT 250) " statement should be issued.
Almost immediately after a server migration project, employees are complaining that they can't reach the Internet. You sit down at a machine and try to ping a well-known website using the host name, which fails. You then try to ping a known public IP address, which succeeds. What is most likely the problem?
a. IP Address of each machine is set incorrectly.b. DNS settings are incorrect.c. Subnet mask is wrong.d. No gateway address is set.
Answer:
b. DNS settings are incorrect
Explanation:
DNS (Domain Name System) settings help to translate web addresses to their IP addresses. Domain Name System servers help to establish a link between human-readable address (host name) and computer readable address (IP address) trough its network.
If the ping to a IP address works but ping to a host name does not, it means that the system interpreting host names to IP addresses doesn't work properly.
Fred has just added DSL service at his home, with a separate DSL modem and consumer-grade router with four Ethernet ports. Fred wants to use the same old phone he was using before the installation of DSL. Which is most likely true about the phone cabling and phone used with his new DSL installation?
a. He uses the old phone, cabled to one of the router/switch device’s Ethernet ports.b. He uses the old phone, cabled to the DSL modem’s ports.c. He uses the old phone, cabled to an existing telephone port, and not to any new device.d. The old phone must be replaced with a digital phone.
Answer:
The answer is letter C.
Explanation:
He uses the old phone, cabled to an existing telephone port, and not to any new device.
Final answer:
Fred can continue using his old telephone by connecting it to an existing telephone port, utilizing a splitter that separates voice calls from DSL data, without the need to connect it to his router or modem, or to replace it with a new digital phone.
Explanation:
Fred wants to know how he can continue using his old phone with his new DSL service. The most accurate option is that he uses the old phone, cabled to an existing telephone port, and not to any new device. This is because DSL service uses the existing telephone line infrastructure for internet connectivity but allows for the simultaneous use of the phone line for standard voice calls.
The DSL modem is connected to the phone line with a splitter that separates the frequencies used for DSL service from those used for voice calls, so the old phone can still be used as before. Fred doesn't need to connect his phone to one of the router's Ethernet ports or the DSL modem's ports, nor does he need to replace the old phone with a digital phone as long as it was working with the telephone line prior to the DSL installation.
In addition to analyzing logic and program code, a project team usually holds a session with users, called a _____, to review the interface with a cross-section of people who will work with the new system and ensure that all the necessary features have been included.
Answer:

Given an initialized String variable message, and given a PrintWriter reference variable named output that references a PrintWriter object, write a statement that writes the string referenced by message to the file in to which output streams.
Answer:
The output streams to this question is "output.print(message)".
Explanation:
The description of the following can be given as:
In the given question it is define a string datatype variable that is "message". Then we create a reference variable of PrintWriter class that is "output" and call string type variable that is message by the use of the print function we print message.Final answer:
To write a string to a file using PrintWriter in Java, use either the println method which appends a newline or the write method with a manual newline. The example code demonstrates both approaches.
Explanation:
To write the string referenced by the variable message to the file using a PrintWriter object referenced by the variable output, you would use the following statement in Java:
output.println(message);
This statement uses the println method to output the string along with an automatically appended newline character which signifies the end of a line. If you were to use the write method instead, you would need to manually add the newline character, like so:
output.write(message + "\n");
In either case, it is essential to manage the ends of lines when writing to a file to ensure the file's content is formatted correctly.
