In this assignment, you are to implement the Digital Signature Algorithm (DSA) as described in the lecture notes. Your program needs to accept a file as an input, and it should produce sig.txt,which is a signature on the input file. You should be able to verify the input file and the signature in sig.txt and this should return True. Otherwise, return False. Write a C++, Java or Python program to accomplish the task.

- Two subroutines in a C# programme create a String object of a given size and a StringBuilder object of the same size, respectively. Utilizing objects from the Timing class that we created at the start of the book, each of the subroutines is timed. Three times are needed to complete this process: once for 100 characters, once for 1,000 characters, and once for 10,000 characters. The times are then given for each size in pairs.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 a program in C programming language. also provide a screenshot that it is workingHere is the question: Write a program that determines the correct input password of an account.

- Java only Design, implement and test a Java class that processes a series of triangles. For this assignment, triangle data will be read from an input file and the program’s output will be written to another file. The output file will also include a summary of the data processed. You must use at least one dialog box in this program. The data for each triangle will be on a separate line of the input file, with the input data echoed and the results referred to by the line number (see example). On initialization, the program will prompt the user for both an input and an output file. If a non-existent input file is specified, the appropriate exception must be handled, resulting in an error message. For the exception case, re-prompt the user for the correct input file. Once the I/O file is specified, the program will read in and process all the entries in the file. The output of the program will be written to the specified output file and echoed to the console. The program will…Write a program in C++ using arrays, C-trings, classes, and libraries. Write a program to handle a user's rolodex entries. (A rolodex is a system with tagged cards each representing a contact. It would contain a name, address, and phone number. In this day and age, it would probably have an email address as well.) Typical operations people want to do to a rolodex entry are: 1) Add entry 2) Edit entry 3) Delete entry 4) Find entry 5) Print all entries 6) Quit You can decide what the maximum number of rolodex entries is and how long each part of an entry is (name, address, etc.). When they choose to edit an entry, give them the option of selecting from the current rolodex entries or returning to the main menu — don't force them to edit someone just because they chose that option. Similarly for deleting an entry. Also don't forget that when deleting an entry, you must move all following entries down to fill in the gap. If they want to add an entry and the rolodex is full, offer them the…Using the linked list, add a sorting function for your program that is able to sort the data according to categories such as staff ID, department or name. The selected sorting method has to produce the most efficient big O notation for your data. Prove the efficiency by comparing various sizes of dataset. You may use any available C++ library or create your own sorting function. You need to submit a short report on this that presents the efficiency of the sorting method.
- Write a C++ program to print the count of word (the) as a separate word in a file named transcript.txt. For example, if the content of the file transcript.txt is: There was a monkey in the zoo. The monkey was very naughty. Then the output of the program should be 2Output the information as a formatted histogram. Each name is right justified with a setw() value of 20. Jane Austen ****** Charles Dickens ******************** I need to know how to output a value in the amount of asterisks. Please help me with this problem using c++.Write a C++ Program to check whether a string is a palindrome or not. A palindrome is a word, verse, or sentence (such as " I ere I saw Elba") that reads the same backward or forward. In this task, the inserted string should consist of letters only (A to Z and a to z). In case of an invalid character is inserted, the output will be the phrase "Wrong entry". If the iserted string is palindrome, the output will be the word "Palindrome", else it will be "NOT Palindrome". The inserted string is case insensitive. IMPORTANT NOTE Do not add any cout statements except for the final answer as specified above. Do not add "Enter a number", "the number of digits is" or any similar prompts. Also note that the automatic grader is case-sensitive; so "palindrome" is wrong but "Palindrome" is right. Do not add any unnecessary spaces inside the strings of cout statements " ". You may add any libraries needed. I/O Program Input: A string consists of letters only Program Output: A phrase that shows…
- Write a C++ program for the following. In each plastic container of Pez candy, the colors are stored in random order. Your little brother only likes the yellow ones, so he painstakingly takes out all of the candies, one at a time, eats the yellow ones, and keeps the others in order so he can return them to the container in exactly the same order as before, minus the yellow candies, of course. Write a program to simulate this process. You must use Nyhoff's stack class; other solutions including the use of the STL stack class are unacceptable. Assume that the candies are denoted as Y for yellow, B for blue, R for red, O for orange. Your program is to query the user for ten letters (representing ten Pez candies), and after using appropriate stack operations, display the contents of the container minus the yellow candies. The order in which the letters are entered is the order that they were removed from the Pez container. When your answer is displayed the results must be in the same…write the following C++ program on 8.5X 11 paper. Please write the program in blue or black ink. Please scan all pages to write the program in order in ADOBE PDF format using ADOBE Scan. Any submissions through email and/or after this deadline will not be accepted. Write a program that plays a game with a single die (or dice). Each number on the die is worth a certain number of points. If the person rolls a six, then that roll is worth 4 points. If the person rolls a five, then that roll is worth 3 points. If the person rolls a three, then that roll is worth 2 points. All the other rolls (four, two or one), that roll is worth 1 point. The rules of the game is that the player rolls the die five times.and adds them up. If the total adds up to a number greater than or equal to 15, then the player gets a rating of excellent. If the total adds up to a number greater than or equal to 12 but less than 15, then the player gets a rating of above average. If the total adds up…Modify the program below to implement exclusive-or (XOR) in Python. AsPython does not natively implement XOR, you will need to implement this by creating an expression using a combination of and, or, and not. Determine what this expression is, and put it in the code below (where “fill in your code here” is written).The starter code below includes the True/True and True/False cases. You should also include the False/True and False/False cases. As a reminder, XOR is only True if exactly one of the inputs is True. Other ways ofthinking about this is that it is True only if one input or the other input is True, but not both. Yet another way of thinking about this is that the result is only True when the inputs are different from each other. SAMPLE STARTER CODE:a = Trueb = Trueresult = # fill in your code hereprint("True XOR True is " + str(result))a = Trueb = Falseresult = # fill in your code hereprint("True XOR False is " + str(result))# Continue for the False/True and False/False…
