Assessment Description Honors Students: Complete this assignment according to the directions provided in the "Honors Addendum," located in Class Resources. This activity has multiple parts. All parts must be completed prior to documentation submission. Part 1: Reading and Writing Text Files. In this activity, you will learn how to read and write text files using non buffered and buffered File I/O classes, then learn how to parse a String into tokens using the String split() method, and finally, how to handle exceptions using various approaches. Part 2: Reading and Writing JSON Files. In this activity, you will learn how to read, write, and serialize JSON files to and from Java Objects. Refer to the instructions within "Activity 4 Guide" to complete the assignment. APA style is not required, but solid academic writing is expected. This assignment uses a rubric. Please review the rubric prior to beginning the assignment to become familiar with the expectations for successful…
JAVA PPROGRAM Write a program that prompts the user to enter a file name, then opens the file in text mode and reads names. The file contains one name on each line. The program then compares each name with the name that is at the end of the file in a symmetrical position. For example if the file contains 10 names, the name #1 is compared with name #10, name #2 is compared with name #9, and so on. If you find matches you should print the name and the line numbers where the match was found. While entering the file name, the program should allow the user to type quit to exit the program. If the file with a given name does not exist, then display a message and allow the user to re-enter the file name. The file may contain up to 100 names. You can use an array or ArrayList object of your choosing, however you can only have one array or ArrayList. Input validation: a) If the file does not exist, then you should display a message "File 'somefile.txt' is not found." and allow the…
C++ Add a search command that asks the user for a string and finds the first line that contains that string. The search starts at the first line currently displayed and stops at the end of the file. If the string is found, the line that contains it is displayed at the top. In case the user enters a string X that does not occur in the file, the program should print the error message: ERROR: string "X" was not found. Attached is the first lines of the .txt file
Word Puzzle GameIn this assignment is only for individual. You are going to decode the scrambled word into correct orderin this game. One round of play is as follows:1. Computer reads a text file named words.txt2. Computer randomly picks one word in the file and randomly scrambles characters in the wordmany times to hide the word3. Computer displays the scrambled word to user with indexes and gives the user options to1. Swap two letters in word based on index given2. Solve the puzzle directly3. Quit the game4. If a player chooses to swap letters, the computer reads two indexes and swaps the letters. Thegame resume to step 3 with the newly guessed word. If the resulted word after swapping is thesecret word, the game is over.5. If a user chooses to solve directly, computer prompts the user to enter the guessed word. If it’scorrect, the game is over, otherwise goes to step 3.6. After game is over, display how many times the player has tried to solve the puzzle.The following is sample…

C++ Programming. Associative and unordered associative containers. Associative containers (set, map, multiset, multimap). • When executing a given task, the input values must be read from a text file. Task : Create a program that deletes a set of elements from a single word of a given string type and creates a second set of elements that consist of a single word, and also displays it on the screen.
readEmpFromFile Implement a function readEmpFromFile that takes a FILE * as the only argument and returns a pointer to a struct employee. This function should read the information from the file (reversing what writeEmpToFile does), create a new employee and fill in the data. If the FILE has no more info (is at end of file), this function should return NULL. This function must also ensure any employee actually created (not the NULL) is added to the array (as is done in createEmployee). Change main to load employees from a file using a command called LOAD which is given to the program using (using your readEmpFromFile function you just wrote). void main(void) { int end = 1; char * command; char buff[256]; char * findEmp; char findBuff[256]; char * sortType; char sortBuff[256]; char hire[] = "HIRE"; char list[] = "LIST"; char quit[] = "QUIT"; char find[] = "FIND"; char fire[] = "FIRE"; char _sort[] = "SORT"; char salary[] =…
In Java Oleae nust read a file A photographer is organizing a photo collection about the national parks in the US and would like to annotate the information about each of the photos into a separate set of files. Write a program that reads the name of a text file containing a list of photo file names. The program then reads the photo file names from the text file, replaces the "_photo.jpg" portion of the file names with "_info.txt", and outputs the modified file names. Assume the unchanged portion of the photo file names contains only letters and numbers, and the text file stores one photo file name per line. If the text file is empty, the program produces no output. Ex: If the input of the program is: ParkPhotos.txt and the contents of ParkPhotos.txt are: Acadia2003_photo.jpg AmericanSamoa1989_photo.jpg BlackCanyonoftheGunnison1983_photo.jpg CarlsbadCaverns2010_photo.jpg CraterLake1996_photo.jpg GrandCanyon1996_photo.jpg IndianaDunes1987_photo.jpg LakeClark2009_photo.jpg…
The python function first_words takes one parameter, fname, the name of a text file, and returns a list containing the first word from each line of the file. For example, if the file contents are: apples are red bananas are yellow limes are green then the list ["apples", "bananas", "limes"] should be returned.NOTE: You may assume the file will contain no blank lines.BIG HINT: If line is a string representing a line of text (inside of a for loop!), then L = line.split() creates a list of the words in the line.
File Stream Problem: Implement a Caesar cipher that can encrypt and decrypt text and file. A Caesar cipher is a substitution cipher that shifts the letters in the original message x spaces ascending the alphabet where x is the key. Example if the key for the cipher is 3, and the message is “I will be there.” Then the coded message would be “L zloo eh wkhuh” Program requirements: Create a class call CCipher that has two member functions encrypt and decrypt. The program should be able to encrypt/decrypt a message from a file as well as a keyboard input. The default key should be 3. The user should be able to select between encrypting and decrypting and should be allowed to do so multiple times until s/he decides to end the program. The file format to be encrypted should be a “.txt” and the user should be able to provide the name of the file to be encrypted, after which the file should be deleted. The user should have the option to view…
