- Create a program in C-Language which details the Basic Enrollment System: Enhanced security and anti-fraud protection -Log in by username and password Upon successful log-in, the system will display the Profile of the Student1st Page: Student Profilelink - https://docs.python.org/3/library/time.html for time module Code - def long_running_task(n): num = 0 for x in range(n): for y in range(n): for z in range(n): num += x + y + z return num print(long_running_task(500))Implement the one-time pad encryption scheme in Microsoft Excel. Your worksheet should look as follows: For Encryption: - Have the message occupy adjacent cells in one row, with one bit of the message in each cell. Align the key (the one-time pad) with the message in the next row. Note that the key should be of the same length as the message. In the next row, enter a formula that computes the ciphertext. Decryption is similar: - Have the ciphertext occupy adjacent cells in one row, with one bit of the ciphertext in each cell. Align the key (the one-time pad) with the ciphertxt in the next row. Note that the key should be of the same length as the ciphertext. In the next row, enter a formula that computes the plaintext (message). .

- ou have been tasked with creating a program to manage a small library. The library has the following books in stock: ```books = { "Harry Potter and the Philosopher's Stone": 5, "The Great Gatsby": 3, "To Kill a Mockingbird": 7, "1984": 4, "The Catcher in the Rye": 2}```The program should use a menu-driven approach to allow the user to select the following desired task: 1. Allow users to check if a specific book is in stock.2. Allow users to add a new book to the library.3. Allow users to remove a book from the library.4. Allow users to apply a discount of 10% to a book if the quantity in stock is greater than 5. (for a given book identified by the user)5. Allow users to apply a discount of 5% to a book if the quantity in stock is between 1 and 5 (for a given book identified by the user) The program should also keep track of the total revenue generated from book sales. Note: your program should be well-commentedMake a c++ program: HOMEPAGE A. Register an account //use function Name: Password: Do you want to register another account? Y or N B. Login Name: Password: //up to 3 trials only, back to homepage if passwords didn't match at 3rd trial //if passwords matched, then go to menu C.Transaction Record //use linked list transaction number balance name transaction amount 0 10,000 lilo withdraw 5,000 D. Account list account no. name password 0 lilo pop MENU Withdraw Deposit Check Balance Homepage ExitChoose a problem that lends to an implementation that uses dynamic programming. Clearly state the problem and then provide high-level pseudocode for the algorithm. Explain why this algorithm can benefit from dynamic programming. Try to choose an algorithm different from any already posted on any other site . Please dont copy from any other site . I need detailed and perfect answer .
- A password is an example of using _____ to authenticate the user. Select one: a. something the user does b. something the user has c. something the user is d. something the user knowsCan someone take a look at my login and signup and tell me if I'm on the right track or doing this completely wrong, please. For context, I'm working on pythonanywhere and using flask. @app.route('/login') def login(): email = request.form.get("email") password = request.form.get("password") table = get_table("Users") item = table.get_item(Key={"email":email}) if 'Item' not in item: return {'result': 'Email not found.'} user = item['Item'] if password != user['password']: return {'result' : "Password does not match."} session["email"] = user["email"] session["username"] = user["username"] result = {'result' : 'OK'} response = make_response(result) remember = request.form.get("remember") if remember == "no": response.set_cookie("remember", "") else: key = str(uuid.uuid4()) table = get_table("Remember") table.put_item(Item={"key": key, "email": user["email"]})…Produce a computer code that shows a program that is subjected to variable attack (one of the attacks of buffer overflow). Any programming language works. Can also use pseudo code and the program does not need to compile (extra credit if works).
