What is the purpose of using BufferedInputStream and BufferedOutputStream classes?

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…

In order for the DumpMem operation to work, what input parameters must be supplied?

If two links to an existing file are created in the same directory as the original (using the link syscall), how many inodes are used to store information about the three directory entries?

Describe scenarios where you might need to wrap an InputStream with other stream types, such as DataInputStream or BufferedInputStream.
