When there are a lot of updates to be made to the data, which of String or String Buffer should be used?
Step by step
Solved in 2 steps
- In Unix You have a record structured file named mydata that has four columns with default delimiter (white space). Sort the file based on its second column and redirect the file to a new file called sortedData.POWERSHELL TASK Try to swap two strings/names in a file and the file name should be a command-line argument.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…
