Question :
Prepare a multithreaded code breaking program. You have been provided 3 files that contain text that have been encrypted using a Caeser cypher scheme.
The task is to figure out the 2 keys used in the scheme. The encryption algorithm looks like:
character = character + key1;
character = character ^ key2; (^ = xor) and encrypts the characters 1 by 1.
Your code requires to decrypt the 3 text files by guessing the 2 keys. You will know you have found the correct keys when you find in the text the string "Dr-Ronald-Marsh".
To get you started, the file HW10-A.dat uses the keys (1, 6) and the file HW10-B.dat uses the keys (25, 44). The file HW10-C uses keys > 0 && < 100.

define the design and application of arrays and how an array simplifies program development. Support your answer with a hypothetical real-world example.
Design a module named getNumber that uses a reference parameter variable to accept an Integer argument. The module should prompt the user to enter a number and then store the input in the reference parameter variable.

assume that queue is a queueType object and the size of the array implementing queue is 100. Also suppose that the value of queueFront is 99 and the value of queueRear is 25.
Generate a unique identification number for each object instantiated from this class. Use a static data member to keep track of the identification number last assigned to an object so that duplications will not occur.
