A good design for a program that reads three letter grades and calculates their average using stepwise refinement would involve the following steps: 1. Input: Collect the three letter grades from the user. 2. Conversion: Convert each letter grade into a numerical value (e.g., A=4, B=3, C=2, D=1, F=0). 3. Calculation: Find the average of the three numerical values. 4. Conversion: Convert the average numerical value back to a letter grade. 5. Output: Display the final letter grade average to the user.
The first step in designing this program would be to identify the input and output requirements. The program will need to accept three letter grades as input and output the average of those grades. To accomplish this, the program will need to prompt the user to enter the grades and store them in variables. Once the grades are stored, the program will need to calculate the average by adding the grades together and dividing by three. Finally, the program will need to output the average.
In conclusion, stepwise refinement is a useful tool for designing software solutions. By breaking down complex problems into smaller sub-tasks, developers can create efficient and effective programs that meet user requirements. For a program that reads three letter grades and calculates an average, the stepwise refinement process could be used to design a solution that meets the input and output requirements, and can be refined and expanded upon as needed.

which type of authentication sends only a hash across the link between two authenticating peers? group of answer choices md5 clear text signed secret keys shared keys
The type of authentication that sends only a hash across the link between two authenticating peers is MD5 (Message-Digest Algorithm 5). It's a widely used cryptographic hash function that produces a 128-bit hash value from the input data, ensuring secure communication between peers.
MD5 authentication is a type of message digest algorithm that is used to verify the integrity of messages transmitted between two peers. In this type of authentication, a hash of the password or a shared secret key is sent across the link between the two peers. The receiving peer then computes the same hash using the same algorithm and compares it to the hash received from the sending peer. If the hashes match, the receiving peer knows that the message has not been tampered with and that the sending peer is authentic.MD5 authentication is considered more secure than clear text authentication, where the password or shared key is sent in plain text over the link between the two peers, because it is much more difficult to reverse engineer the hash and obtain the original password or shared key. However, MD5 authentication is not as secure as signed secret keys or shared keys, which use more complex encryption algorithms to ensure secure communication between two peers.

To modify the table relation so that when a record is updated in the department table, the related record in the professor table will also be updated, you need to create a foreign key constraint between the two tables.
This can be done by identifying the common field(s) between the tables, usually the primary key of the department table and a foreign key in the professor table. Once the constraint is created, any changes made to a record in the department table will automatically be reflected in the related record in the professor table. This ensures data consistency and accuracy across both tables. So, whenever a record is updated in the department table, the modification will cascade to the professor table as well, and the related record will also be updated accordingly. One-to-one relationships aren’t the most common, since in many cases you can store corresponding information in the same table. Whether you split up that information into multiple tables depends on your overall data model and design methodology;

Scenario You are doing a fantastic job at Chada Tech in your new role as a junior developer, and you exceeded expectations in your last assignment for Airgead Banking. Since your team is impressed with your work, they have given you another, more complex assignment. Some of the code for this project has already been completed by a senior developer on your team. Because this work will require you to use both C++ and Python, the senior developer has given you the code to begin linking between C++ and Python. Your task is to build an item-tracking program for the Corner Grocer, which should incorporate all of their requested functionality. The Corner Grocer needs a program that analyzes the text records they generate throughout the day. These records list items purchased in chronological order from the time the store opens to the time it closes. They are interested in rearranging their produce section and need to know how often items are purchased so they can create the most effective layout for their customers. The program that the Corner Grocer is asking you to create should address the following three requirements for a given text-based input file that contains a list of purchased items for a single day: Produce a list of all items purchased in a given day along with the number of times each item was purchased. Produce a number representing how many times a specific item was purchased in a given day. Produce a text-based histogram listing all items purchased in a given day, along with a representation of the number of times each item was purchased. As you complete this work, your manager at Chada Tech is interested to see your thought process regarding how you use the different programming languages, C++ and Python. To help explain your rationale, you will also complete a written explanation of your code’s design and functionality. Directions One of Python's strengths is its ability to search through text and process large amounts of data, so that programming language will be used to manage internal functions of the program you create. Alternatively, C++ will be used to interface with users who are interested in using the prototype tracking program. Grocery Tracking Program Begin with a Visual Studio project file that has been set up correctly to work with both C++ and Python, as you have done in a previous module. Remember to be sure you are working in Release mode, rather than Debug mode. Then add the CS210_Starter_CPP_Code and CS210_Starter_PY_Code files, linked in the Supporting Materials section, to their appropriate tabs within the project file so that C++ and Python will be able to effectively communicate with one another. After you have begun to code, you will also wish to access the CS210_Project_Three_Input_File, linked in the Supporting Materials section, to check the functionality and output of your work. As you work, continue checking your code’s syntax to ensure your code will run. Note that when you compile your code, you will be able to tell if this is successful overall because it will produce an error message for any issues regarding syntax. Some common syntax errors are missing a semicolon, calling a function that does not exist, not closing an open bracket, or using double quotes and not closing them in a string, among others.
Create code to determine the frequency of a specific item. Here you will be addressing the second requirement from the scenario to produce a number representing how many times a specific item was purchased in a given day. Remember an item is represented by a word and its frequency is the number of times that word appears in the input file. Reference the following to help guide how you can break down the coding work.
Use C++ to validate user input for option 2 in the menu. Prompt a user to input the item, or word, they wish to look for. Write a C++ function to take the user’s input and pass it to Python.
Write Python code to return the frequency of a specific word. It will be useful to build off the code you just wrote to address the first requirement. You can use the logic you wrote but modify it to return just one value; this should be a fairly simple change (about one line). Next, instead of displaying the result on the screen from Python, return a numeric value for the frequency of the specific word to C++.
Write a C++ function to display the value returned from Python. Remember, this should be displayed on the screen in C++. We recommend reviewing the C++ functions that have already been provided to you for this work.
One approach is to use the Python/C API to write a C++ function that passes user input to Python, which then uses a dictionary to count the frequency of each word in the text file and returns the frequency of the specific word.
How can you use C++ and Python together to determine the frequency of a specific item in a text file?To address the second requirement from the scenario and create code to determine the frequency of a specific item, you can follow these steps:

The method that is not a banking service delivered remotely is "face-to-face." Internet and mobile phone banking services are both considered remote delivery methods, as they allow customers to access their accounts and perform transactions without visiting a physical bank location. Face-to-face banking, on the other hand, requires customers to visit a bank branch and interact with bank employees in person.
Explanation:
Face-to-face banking requires customers to physically visit a bank branch to conduct their banking transactions. In this case, the customer has to travel to the bank's location and interact with the bank employees in person to avail the services offered by the bank. This method of banking is considered a traditional method of banking delivery and is not a remote service as it requires physical presence.
On the other hand, internet and mobile phone banking are considered remote delivery methods because they enable customers to access their accounts and perform transactions from their preferred location, without the need to visit a physical bank branch. These remote delivery methods provide customers with convenience and flexibility as they can access their accounts 24/7 from any location with an internet or mobile phone connection.
Internet banking allows customers to perform a range of banking transactions such as checking account balances, transferring funds, paying bills, applying for loans and credit cards, and more.

The given statement "In iOS, setting up tables can be done mostly using Storyboard and very little code" is True because iOS developers can use Storyboard to set up tables with ease, and rely on code only for more advanced functionalities
The Storyboard is a visual tool in Xcode that allows developers to design and layout user interfaces (UI) for their applications without having to write a lot of code. With Storyboard, you can create and customize UITableViews, which are used for displaying tables in iOS apps. When you create a new UITableView in Storyboard, you can easily configure its properties, such as the style (plain or grouped), the number of sections, and the number of rows per section. Additionally, you can design and customize table view cells directly in the Storyboard by adding labels, images, or other UI elements.
To connect your table view to your code, you'll need to create an IBOutlet for the UITableView and set up UITableViewDataSource and UITableViewDelegate protocols. These protocols define the methods needed to populate the table with data and handle user interaction, such as cell selection or row editing. However, the amount of code required is minimal compared to setting up the entire table view programmatically.
In summary, using Storyboard for setting up tables in iOS apps simplifies the process and reduces the amount of code needed, making it a convenient and efficient tool for developers. It allows for easy customization of the UI elements and streamlines the connection between the interface and the app's code.

The syntax for a multi-catch exception in Java is to use a single try block with multiple catch blocks, each catching a different type of exception. This allows for handling multiple exceptions in a more concise way.
In Java, there are two categories of exceptions: checked and unchecked. Checked exceptions are checked at compile time and must be handled explicitly by the programmer. Unchecked exceptions are not checked at compile time and can be handled implicitly or left unhandled.
Exceptions can also be categorized as runtime or compile-time. Runtime exceptions are thrown during the execution of a program, while compile-time exceptions are thrown during the compilation of a program.
Some exceptions are considered critical, meaning they can cause the program to terminate unexpectedly. These types of exceptions should be handled carefully to ensure the program continues running smoothly.

Lines of code that could create an exception are sent to what type of block?1. finally block2. try block3. exception block4.catch block
Lines of code that could cause an exception are enclosed in the `try` block, which catches exceptions in the `catch` block.
In Java, the `try-catch-finally` block is used for exception handling. The `try` block encloses the code that may throw an exception. If an exception is thrown, the control is transferred to the `catch` block, which catches the exception and handles it appropriately. The `finally` block is used to enclose code that must be executed, regardless of whether an exception occurs or not. It is typically used for cleanup code such as closing a file or database connection. The `try-catch-finally` block ensures that the program doesn't crash if an exception occurs and provides a way to handle errors gracefully.

FILL IN THE BLANK. the code to create a random integer between 1 and 100 is __________(random * 100) + 1.
To a random integer between 1 and 100 using the provided code, "Math.floor()". This code will generate a random number between 1 and 100, inclusive.
The code to create a random integer between 1 and 100 is a bit more complex than. To generate a random integer in this range, we need to use a combination of the random() function and some basic arithmetic. First, we need to call the random() function, which generates a random decimal number between 0 and 1. We can then multiply this decimal by 100 to get a random decimal between 0 and 100.
However, we don't want a decimal - we want a whole number. To get this, we can use the floor() function, which rounds a decimal down to the nearest whole number. So if we take the floor of our decimal multiplied by 100, we get a random integer between 0 and 99.

Which layer provides logical addressing that routers use for path determination?
The layer that provides logical addressing that routers use for path determination is the Network layer (Layer 3) of the OSI model.
The layer is responsible for addressing and routing packets across multiple networks to their destination using logical addresses such as IP (Internet Protocol) addresses.
Routers use this logical addressing information to determine the best path for a packet to take through the network, and to forward the packet to the next hop on that path.
The Network layer (Layer 3) of the OSI model is the layer that offers the logical addressing that routers utilise to choose a path.
The layer is in charge of employing logical addresses like IP (Internet Protocol) addresses to address and route packets across various networks to their destination.
These logical addressing details are used by routers to identify the most efficient route for a packet to take through the network and to send the packet to the following hop on that route.

____________ occurs when a higher-priority process needs to access a data structure that is currently being accessed by a lower-priority process.Select one:a. Deadlockb. Priority inversionc. A critical sectiond. A race condition
a.Priority inversion : occurs when a higher-priority process needs to access a data structure that is currently being accessed by a lower-priority process.
In this situation, the higher-priority process is forced to wait until the lower-priority process completes its access to the data structure. This can lead to unexpected delays in the execution of the higher-priority process and potentially impact the overall performance of the system.
To handle this issue, synchronization mechanisms, such as semaphores or mutexes, are often used to protect critical sections. A critical section is a portion of code where shared resources are accessed, and proper synchronization ensures that only one process can enter the critical section at a time.
If not properly managed, priority inversion can lead to other issues like deadlocks or race conditions .A deadlock occurs when two or more processes are stuck, waiting for each other to release a resource. On the other hand, a race condition occurs when the behavior of a system depends on the relative timing of events, causing unpredictable outcomes.
