Code Example 9-1 struct Product { string name; double price; int quantity; }; (Refer to Code Example 9-1.) Given a Product object named product, which of the following statements would you use to display the value of the name data member on the console? a. cout << product::name; b. cout << product.name; c. cout << product("name"); d. cout << product[0];
Answer:
a. cout << Product ::name;
Explanation:
Computer software use different languages which helps user to initiate command. When a user initiates command the results are displayed according to input command. If product name is required as output then insert command should be product::name; this will display names of different products present in the system.
Explain the purpose of the open() and close() operations.
Answer:
The open() operation notifies the system that the named file is about to become active. The close() operation notifies the system that the named file is no longer in active use by the user who issued the close operation.
How to prepare and draw a corresponding flowchart to compute the sum and product of all prime numbers between 1 and 50
Answer:
Create boxes with the following content
Initialize sum to 0, product to 1 and number to 1Check if number is a prime. If yes, update sum += number and product *= numberIncrease number by 1If number is <= 50, go back to "check" block.The check block has a diamond shape.
At the "yes" branch of the check block, you can create separate blocks for updating the sum and the product.
Connect the blocks using arrows.
Indicate the start and the end of the flow using the appropriate symbols.
The block to check if a number is a prime you could further decompose into the steps needed to do such a check.

g Add a throw statement to the processNumbers function that throws the message "An element in the list is not a number." if one of the elements in toProcess is not a number. Hint: The function isNaN() returns true if the parameter is not a number.
Answer and Explanation:
function processNumbers(alist){
var Ourarray= new array(alist);
Ourarray.foreach(
if(isNaN()){
Console.log( "An element in the list is not a number."};
break;
}
}
processNumbers(alist)
From the above, we have defined a function that takes an array parameter(the following array variable will make sure of that). We test each element in the array using foreach array function. The for each function runs the if statement and if isNan is true for each of the elements in the array.

Select the correct statement(s) regarding IP addressing.
a. IPv4 and IPv6 addressing is fully compatible with one another.
b. CIDR address format represents a Class C network only used within an intranet.
c. Subnet masks are used with both class and classless IP addresses.
d. all statements are correct.
Subnet masks are used with both class and classless IP addresses is the correct statement. Therefore, the correct option is C.
What is an IP address?A device on the internet or a local network may be identified by its IP address, which is a special address. The rules defining the format of data delivered over the internet or a local network are known as “Internet Protocol,” or IP.
Only C is correct, rest other statements are incorrect because:
a. IPv4 and IPv6 addressing is fully compatible with one another is incorrect. While IPv4 and IPv6 can coexist on the same network, they are not fully compatible with one another.
b. CIDR address format represents a Class C network only used within an intranet is incorrect. Classless Inter-Domain Routing (CIDR) is a technique used to allocate IP addresses more efficiently.
Therefore, subnet masks are used with both class and classless IP addresses is the correct statement. Therefore, the correct option is C.

I connected to an external hard drive to transfer some photos from my vacation. When I try to drag the photo, it bounces right back and does not transfer. What is the likely cause of this issue?
a. hard drive is full
b. photos were taken in a different country
c. USB port is broken
d. the file structure of the 2 hard drives are not compatible
The answer is D, What is the likely cause of this issue is that the file structure of the two hard drives are not compatible.
The file structure or file system, of a hard drive, tells the disk how to read, write and store information on the drive. Some file systems do not allow the disk to store any files and often do not display error messages. If we try to drag a file onto a hard drive with this kind of file structure, the action would simply not be performed. This can be fixed by formatting the disk partition into a new file system.
Option B states that the issue may be that the photos were taken in a different country. This is not the cause of the problem because regardless of where the pictures are taken, they are all stored in common formats such as:
JPEGPNGJFIFAny external hard drive capable of storing images will have the ability to receive files in these formats as well as many other image formats. For this reason, option B is False.
The question states that you were able to connect the external Hard drive and drag files onto it, though unsuccessfully. This tells us that the USB port is working as intended, if it were not working, it would not display the Hard drive onto the computer and we would not be able to drag files to it. Therefore, option C is false
Insufficient Hard drive storage space is a common issue in not being able to transfer files between hard drives. However, if this were the case, the user would be shown a message displaying the error. The message may look like:
"Insufficient space on the disk.""The Disk is full.""Not enough memory to complete this action"The exact wording may vary depending on the operating system in use. Since the question states that the files simply "bounces back" without an error message displaying, we can infer that option A is false.

Why are data silos problematic?
Answer:
Hampers collaboration
Resource wastage
Lack of data integrity
Explanation:
Data silos comes into play When different departments of an orgainiziations independently collects data needed for its operations. The finance, HR, administrative departments and so on collects their data and keeps it to themselves. As a result there is a repetitive and needless gathering and storage of already existing data, that is the data required by one group will have to be gathered again while it currently exists with another group. This leads to inefficient resource management and wastage. This practice also leads to data integrity as data stored differently across departments becomes inconsistent and less accurate over time. Team work and collaboration is gradually eroded as each group continues to hold on to its resources which poses a problem towards organizational growth.
