In this assignment you will be writing several functions that process files and dictionaries to encryptand decrypt messages. A dictionary will be used to create a random substitution cypher. Each letterof the alphabet will be mapped to another random letter in the alphabet. No letter will map or bemapped to any duplicate letter. For example given the partial dictionary below you can encrypt amessage.Be sure to use the starter file provided so you can see the appropriate outputs. Be sure to downloadand place the appropriate text files in the same directory as your python file.

A File was sorted by key field, and then 10 records were stored in each block. Multi-level Indexing is made here, and 100 indexes are stored in each block. To find a specific record, the total number of block accesses is less than 4. Calculate the maximum number of records that make up this file.
SAME PARAMETERS: In the RENTALS table shown in fig 2, 40 customers have created 50 rental contracts over time. A RENTALS record is 122 bytes and the block size for your OS is set to 1024 bytes with each block having a 1 byte pointer to the next written block as well as a 1 byte pointer to the next physically consecutive block.   Assuming spanned organization, how many blocks do you estimate the RENTALS file is using at its current size? multiple choice a.50 b.6 c.400 d.7
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…

A file has r=30,000 EMPLOYEE records of fixed-length. Consider a disk with block size B=512 bytes. A block pointer is P=6 bytes long and a record pointer is P R =7 bytes long. Each record has the following fields: NAME (30 bytes), SSN (9 bytes), DEPARTMENTCODE (9 bytes), ADDRESS (40 bytes), PHONE (9 bytes), BIRTHDATE (8 bytes), SEX (1 byte), JOBCODE (4 bytes), SALARY (4 bytes, real number). An additional byte is used as a deletion marker. a) Calculate the record size R in bytes. b) Calculate the blocking factor bfr and the number of file blocks b assuming an unspanned organization. c) Suppose the file is ordered by the key field SSN and we want to construct a primary index on SSN. Calculate the index blocking factor bfr i.
Consider the binary file named, "Course_Data" whose format is below. Each record represents a course with a single letter grade, a numerical grade, and the number of assignments in the course. Write a block of code to read the first 200 records and find and print the average of all courses whose letter grade was an "A". Maximum 20 lines of code for credit. (Assume all libraries are included) File format:{ char LGrade; // Letter Grade: A, B, C, D, F (Single letter) int NGrade; // Number Grade: 0 - 100 int NOA; // Number of assignments: 1 - 20}
Problem:A company has stock of many goods, and they want to filter the stock so that some of the materials can go on sale. The stock information recorded in a file"data.txt" as shown in the sample. (in the following sequence)(item name, price_perunit, profit, months_of_stocking, customer_reviews )The sale policy of the company depends on many factors according to the following. • if item in stock more than 8 months and item profit is more than average profit of all items o yes - if customer reviews low quality ● yes – sale 50% ● no – if customer reviews medium quality o yes – sale 30% o no – sale 15% o no- if item profit more than 8% of the item price ● Yes – if in stock more than 1 year o yes-sale 40% o no- not on sale ● No - not on sale Write a C++ program that reads the information from “data.txt” input file into 5 arrays, then processes these arrays to produce three arrays, first array holds the items on sale, second array holds percentage of sale , and the third one holds the…
Write comparators for the type File to order by increasing/decreasing order of file size, ascending/descending order of file name, and ascending/descending order of last modification date. Use these comparators in a program LS that takes a command-line argument and lists the files in the current directory according to a specified order, e.g., "-t" to sort by timestamp. Support multiple flags to break ties. Be sure to use a stable sort
With linked allocation, each file is a linked list of disk blocks; the disk blocks may be scattered anywhereon the disk. The directory contains a pointer to the first and last blocks of the file. Each block contains a pointerto the next block. Refer to the illustration below.
