For this assignment, you must implement the Data Encryption Standard (DES) algorithm with any programming language that you are comfortable with. The recommendation is to use C/C++ or Java. You can accomplish this assignment individually or by forming a team of 2 students. You can utilize the publically available tables/functions in order to implement the DES. You can find these permutation tables/functions in some reference books or over the Internet. You algorithm should get a plaintext as well as a "secret key" from the user and then perform encryption (generating the ciphertext from the plaintext) and decryption (generating the original plaintext from the ciphertext). You can also select any "mode of operations that you want. All the necessary technical materials are available in the posted lectures on Canvas. You must submit all related files in a zip file on Canvas (just one file for each group, submitted by the group leader). Make sure to include a "ReadMe.txt" file so that I know what you have done and how your program can be executed.

Write a c++ program to simulate a coffee shop or a Mcdonald's drive-thru where different customers give an order and they receive a unique ID then you use Queue Data Structure to arrange the order and use a sorting algorithm to sort identical orders so that you can make your entire servicing faster at the end the customer is given a receipt with his order, price, and ID on it. Make sure to use classes.
I want to be able to generate a password that contain actually words but that at the same time it provided a desirable length. This is what I have so far... words = ['car', 'telephone', 'paper', 'university', 'smart', 'major', 'study', 'study', 'work', 'art', 'pencil''pen', 'notebook', 'library', 'student', 'number', 'news', 'laptop', 'screen', 'computer', 'keyword','finances', 'technology', 'life', 'career', 'job', 'hello']punctuation = string.punctuationnumbers = string.digits def as_asking():print("Welcome to the password generator") length = input('Enter the length of password (at least 5): ') return str(length) def a_password(): word = random.choice(words)num = random.choice(numbers)punct = random.choice(punctuation) combine = str(word) + str(num) + str(punct) return combine I want to create a new function that calls on the other two functions and outputs a password that is random with the length given...
The task is to implement part of a linter program using python. Specifically, you must be able to scan for grouping symbols ( "()", "[]", "{}") and ensure that there are no hanging open symbols or stray closing symbols in the source file. There will be files you will need to scan so you need the open() in your code. Also, you can use the read() or readlines() to know which lines has no opening or stray closing symbols. Example: You scan this code from a file, and you notice that there is a stray closing symbol ")". 1 int main(void) { . 123 2 3 4 printf("Hello world")); return 0; } The implementation must involve recursion in terms of scanning for the scope. If a different closing symbol is encountered or the end of file is reached, the error message "Line : missing closing symbol for "" should be displayed. For stray closing tags, the message "Line : stray closing symbol for "". Do not use "stack" in your code.
Write a c++ program that reads a list of enrollments from a file and prints a class roster for the teacher. Make the class roster lineup as neatly as you can and still fit on the screen.You can choose the actual values to use for your data. Make sure to do enough sets of data to well test your program!(Empty data set, normal data set, data with large values, data with short values, etc.)Also, your program can't know ahead of time how many people are enrolled in the class...Don't forget to read the file's name from the user and protect your program against any errors that may occur during theopening of the file.Try to use functions to break up the program into more manageable pieces.As an example, you might have the data file contain:# name# student number# address1# address2# phone number# majorJason James100400299400 Maple DrWestfalia, HI 66554555/555-1122Computer ScienceFaruk Ahmed1112223331200 West Jones AveSlimsville, PQ 22221332-4546Medeaval French PoetrySean…
Write the python3 code for the given problem.... Please write C++ code also.... It's urgent!!!!!!!!!!
When an author produces an index for his or her book, the first step in this process is to decide which words should go into the index; the second is to produce a list of the pages where each word occurs. Instead of trying to choose words out of our heads, we decided to let the computer produce a list of all the unique words used in the manuscript and their frequency of occurrence. We could then go over the list and choose which words to put into the index. The main object in this problem is a "word" with associated frequency. The tentative definition of "word" here is a string of alphanumeric characters between markers where markers are white space and all punctuation marks; anything non-alphanumeric stops the reading. If we skip all un-allowed characters before getting the string, we should have exactly what we want. Ignoring words of fewer than three letters will remove from consideration such as "a", "is", "to", "do", and "by" that do not belong in an index. In this project, you…
Write a code in Python that will look for some patterns (or lack of patterns) in data. More precisely, it will investigate how often various digits appear as the first digit and the last digit of numerical data of various kinds.
I need to make a program in C language of the game of 15, in which the 15 numbers have to be ordered on a board with 16 spaces and the remaining space is the empty space, I have to do it with linked lists. Only to manipulated, not solved, using commands like u(up), d(down), l (left) and r (right), then the space must be moved and the puzzle will be displayed.
Is it possible to quickly access frequently used operators while dealing with enumeration types, such as the arithmetic operators and the stream operators? Is it possible to get a satisfying outcome by, say, overloading these operators? What are the benefits and drawbacks of this approach?

Write a C++ program to produce the first 90 Fibonacci numbers. A Fibonacci number is one that I is the product of the prior two generated numbers. The sequence is seeded with the values of O and 1, so that the sequence starts off as 0 1123. Fibonacci numbers are used in computing hash table locations for file management systems.
This question was rejected because lack of a text file, which I do not see a way to upload. I saved the first part of the file as an image because that is all I can upload. If that doesn't suffice, please advise how to include a text file. In C++, I would like some help improving or making a better password lookup function for a Hash Table class/program I made, The function: it is supposed to lookup a user password using their ID and name which I read in from a text file. The one I have only works for the first 10 records, which I highlighted below in the program. string lookupPassword (string inUserID, string inUserName){ string thePassword; ... return thePassword; } Here is part of the program thus far: // Hash.cpp #include <iostream>#include<string>#include<iomanip>#include<fstream>using namespace std;//node classclass nodeBST {private: //user data string userID; string userName; string userPW; //BST left and right children nodeBST*…
