Programmable Logic Controller (PLC): PLC is a specialized computer used in industrial segments to control machines and process. PLC is program that consists of a set of instructions which resembles the controlling functions needed to perform specific tasks. The function of PLC is similar to that of a relay and hence, in an industrial segment a relay is greatly replaced by a suitable PLC. When compared to general Personal Computer (PC), a PLC is available in small and tiny sizes. The basic architecture of a PLC consists of an input-output interface module and a small Central Processing Unit (CPU) that runs by controlling programming language. Hexadecimal number system: In hexadecimal number system, the numbers from “0” to “9” and letters from “A” to “F” are used. It means, in total, hexadecimal system has 10 numbers and 6 alphabets. Therefore, the base used for hexadecimal numbering system is 16. Binary number system: In binary system, the numbers “0” and “1” are only used. It means, in total, binary system has only 2 numbers. Therefore, the base used for binary numbering system is 2.

Write a program that simulates a Magic 8 Ball, which is a fortune-telling toy that displays a random response to a yes or no question. In the student sample programs for this book, you will find a text file named 8_ball_responses.txt. The file contains 12 responses, such as “I don’t think so”, “Yes, of course!”, “I’m not sure”, and so forth. The program should read the responses from the file into a list. It should prompt the user to ask a question, then display one of the responses, randomly selected from the list. The program should repeat until the user is ready to quit. Contents of 8_ball_responses.txt: Yes, of course! Without a doubt, yes. You can count on it. For sure! Ask me later. I'm not sure. I can't tell you right now. I'll tell you after my nap. No way! I don't think so. Without a doubt, no. The answer is clearly NO. (You can access the Computer Science Portal at www.pearsonhighered.com/gaddis.)
