Inventory Items:
We're going to do an inventory management system. In the real world, this would use a database, not a file. A single inventory item contains:
item names (or description), like "socks, - red" or "socks - blue". This has to be a character string that WILL include spaces.
item numbers that are unique to the item, similar to UPC codes, like 121821 or 128122. Even though they look like numbers, they are really character strings.
a price, like 4.99, a double.
a quantity on hand, like 13, an integer.
Your program will need to manage arrays of these items.
-----------------------------------------------------------------------------------
Menu:
Your code need to have the following features, all accessible from a menu.
Add a new inventory item to the data into the array in memory. You'll type in the inventory number, description, quantity and price. This will also update the number of items on the menu screen.
List the inventory (in the array in memory) on the screen in neat columns. Display it in chucks of 15 items with a pause in between.
Search the inventory (in the array in memory) for an item by inventory number. If found, print the stored info, otherwise print 'not found'.
Calculate the total value on hand of the inventory (in the array in memory). The sum is the accumulation of all the (quantities * prices).
Save the array in memory to a disk file. It can then be loaded later.
Read from a disk file to the array in memory. This will overwrite the array in memory with new information from the disk. If you data isn't saved, it will be lost. That how is SHOULD work!
----------------------------------------------------------------------------------------------------------------------------------------
----------------------------------------------------------------------------------------------------------------
Menu Sample:
56 items stored
1) Add an item to memory
2) Search memory for an item
3) List what's in memory
4) Total value on hand
5) Save to a file
6) Read in from a file
0) Exit Program
Enter Choice:
-------------------------------------------------------------------------------------------------------------------
How to store the arrays: Parallel Arrays Option
You can maintain 4 arrays, one for each type. You will need to be careful to keep the items in the same position.
string descriptions[1000];
string idNumbers[1000];
float prices[1000];
int quantity[1000];
In this scenario, an item will be spread over the 4 arrays, but all at the same index.
------------------------------------------------------------------------------------------------------------------------------
How to store the data on the disk:
You are required to use the following text based format
Socks - Blue (in the inventory file)
74627204651538
4.99
27
Yellow Socks
25435567456723452345
7.99
27

Explain how any simple substitution cipher that involves a permutation of the alphabet can be thought of as a special case of this cipher.
A simple substitution cipher takes each vector ([tex]e_i[/tex]) and assigns it to the vectors [[tex]e_{\pi (i)}[/tex]] in a one-to-one function so as to make them equivalent.
What is the Hill cipher?In 1929, the Hill cipher was invented by Lester S. Hill and it can be described as a poly-graphic substitution cipher that is typically based on linear algebra and it avails a cryptographer an ability to simultaneously operate on more than three (3) symbols.
In Cryptography, the simple substitution cipher is usually viewed as a function which takes each plaintext letter (alphabet) and assigns it to a ciphertext letter. Thus, it takes each vector ([tex]e_i[/tex]) and assigns it to the vectors [[tex]e_{\pi (i)}[/tex]] in a one-to-one function so as to make them equivalent.

With SAN technology, servers use a separate network to communicate with the storage device. Group of answer choices True False
Answer:
true
Explanation:
Write a class with methods to help you balance your checking account (an object class-main method is not in this class). The CheckingAccount Class should have at least two instance variables: the balance and the total service charges, along with methods to get and set each instance variable. You may add other variables and methods if you like. The program should read the initial balance for the month, followed by a series of transactions. For each transaction entered, the program should display the transaction data, the current balance for the account, and the total service charges. Service charges are $0.10 for a deposit and $0.15 for a check. If a check forces the balance to drop below $500.00 at any point during the month, a service charge of $5.00 is assessed but only for the first time this happens. Anytime the balance drops below $50.00, the program should print a warning message. If a check results in a negative balance, an additional service charge of $10.00 should be assessed. A transaction takes the form of an int number (the transaction code), followed by a double number (the transaction amount). If the int number is a 1, then the double number is the amount of a check. If the int number is 2, then the double number is the amount of a deposit. The last transaction is 0 with no number to follow it. Use the JOptionPane to produce the dialog. A sample Input/Output dialogue is provided via the Sample Run Link below. Use proper style and indentation, efficient programming techniques and meaningful variable and method names according to Java conventions.Code Template The following code template will help with this assignment:----------------- Main.java ------------------------public class Main { // global variables // define a CheckingAccount object to keep trach of the // account information public static void main (String[] args) { // defines local variables CS 3 – Spring 2017 E. Ambrosio 2 // get initial balance from the user // perform in a loop until the transaction code = 0 // get the transaction code from the user // and process it with appropriate helper method // When loop ends show final balance to user. } public static __________ getTransCode() { } public static _________ getTransAmt() { } public static __________ processCheck(___________) { } public static __________ processDeposit(___________) { } } --------------------CheckingAccount.java ------------------------- public class CheckingAccount { private double balance; private double totalServiceCharge; public CheckingAccount(double initialBalance) { balance = ______________________; totalServiceCharge = ______________; } public ____________ getBalance() { return _______________; } CS 3 – Spring 2017 E.
