Show a single command (or multiple commands joined with an appropriate operator) that would show the percentage of allocated disk space actually used at present for the "/home" file system only.

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

I have to create a program that will create a database when using geo points. I will include a previous program and the instructions: You are going to change program 8 so that instead of reading in a list of five or more points from a file you will read the points in from a database. Create a program the will create your database and insert at least five points. Use your own data, something like: 100, 200, 123, Main Campus 120, 133, 142, Montoya 153, 123, 322, Rio Rancho 133, 123, 143, STEMULUS Center 153, 142, 122, ATC   Run your initialization code to create the database. Modify your GUI program from program 8 so that it reads points from your database instead of a file. Turn in the initialization code, the database and your new GUI program.

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…
