Create a program that simulates a simple registration and login function. Your program should access, write, edit and update data in the credentials.csv file. Note: Create your own credentials.csv file. Add one record having the following value: Juan Dela Cruz, January-1-1995, jdc_000@yahoo.com, Admin, 123456 STEP 1: At the start of the program execution, it should prompt the user of the following options: Register Login STEP 2: If the user chose option #1, the program will prompt the user on the following fields: First Name Middle Name Last Name Date of birth Email address Username Password Confirm Password STEP 2a: Password and Confirm Password should match, thus, incorrect inputs on those 2 fields should not be accepted. STEP 2b: After filling up the fields correctly, the program will then display the following: Display Profile Reset Password Log-out STEP 2c: Options #1 - Display Profile and #2 - Reset Password’s functions are optional.

Add a command to this chapter’s case study program that allows the user to view the contents of a file in the current working directory. When the command is selected, the program should display a list of filenames and a prompt for the name of the file to be viewed. Be sure to include error recovery in the program. If the user enters a filename that does not exist they should be prompted to enter a filename that does exist.
Instructions Your job is to write a program to encrypt outgoing messages and decrypt incoming messages using a Vigenere Cypher. In this assignment, you will parse a string of words from a file into tokens using the strtok_s command with pointers and then use the Vigenere Cypher algorithm to encrypt and decrypt the parsed words. Before you can perform any encryption/decryption activities, the first step is to read in messages from a file and parse the messages into individual words. The Program: Setting up classes and understanding tokenization The first step in encrypting/decrypting messages is to parse the messages into words before applying the encryption/decryption algorithms to them. This parsing process is called “tokenization.” Read the contents of a file into this array using the getline command. The objective of this assignment is to demonstrate the use of pointers in a program utilizing c-strings and tokenization. The use of pointers is foundational in C++. This…
Using Java, create a personal directory that contains a data structure for first name, last name, email address and phone number. The data structure should be able to contain the information for an unlimited number of people (depending on system resources).• The program interface should consist of a menu that provides the user with ways to (at least):▪ Add: Get data from user and add the data to the structure.▪ View: which will view the current data in the directory ▪ Edit/Update: Edit existing data ▪ Remove: Delete an entry▪ Search: which prompts the user for search criteria (program should be smart enough to know how to tell what kind of data is being searched for. Try to make this as versatile as possible). Display the data if found. If not found add the new information to the data structure (you must provide the right input for this).The program should store the data in a file so that the program can be run whenever the user wants, even after closing.• Your program should:▪ Contain…

Explain in detail what you consider a file extension to be and what function you think it fulfills. Go to a random folder on your computer and name three file extensions you see there, as well as any software programs that may have produced them. Most file extensions should be shown by simply right-clicking on a chosen file and choosing properties from the pop-up menu (Microsoft Windows environment).
READ the Scenario listed below. Once you read the Scenario, answer the questions listed. You are not required to do any programming. SCENARIO As a developer you have been asked to work with a team that is developing a Student Information System. For your part of the project you have been asked to do the tasks listed below (do not actually do anything) . • Create a file EXSTUD that will be given to a user to enter data. This file will be accessed by another developer's program. • Create a program EXPGM1. a How would you create your file? b What IBM i Utility would you use to enter data into the file? c What type of object/attribute would the data file be created as? d What needs to be done with the program code to make it executable? e List the full command to execute the program you are to create? f What type of object would the Program be created as? g Where exactly would you put your program code?
