An ISBN (International Standard Book Number) is a 10 digit number that is used to identify a book. The first nine digits of the ISBN number are used to represent the Title, Publisher and Group of the book and the last digit is used for checking whether ISBN is correct or not. To uniquely identify a book a 10-digit ISBN number is used. The rightmost digit is checksum digit. This digit is determined from the other 9 digits using condition that 10d, + 9dz + 8dg + + d4o must be a multiple of 11 (where d, denotes the i" digit from the right). The checksum digit d; can be any value from 0 to 10: the ISBN convention is to use the value X to denote 10. Write a C program using pointers that receives a 10- digit ISBN, and computes the checksum, and reports whether the ISBN number is correct or not. Example: 007462542X = 10°0 + 9*0 + 8*7 + 74 + 6*6 + 5*2 + 4*5 + 3"4 + 2*2 + 110 = 176 Since 176 leaves no remainder when divided by 11, hence it is a valid ISBN. Note: When the check digit turns out…

The condition to press the buttons in front of two competitors after reading the question in a quiz. They can answer questions with. When the button is pressed, the competitor who pressed first the light is on (when the digital is 1, the lamp lights up). 10 seconds to answer the question there is. If the question is not answered after the time is over, the lamp in front of the competitor turns off and the second The contestant can answer the question by turning on the lamp in front of him by pressing the button. As a result of pressing the button in front of the competition, the game of all competitors can be rotated. (When the buttons are pressed, the digital zero signal goes to the microcontroller.) Write the necessary software for the relevant competition with Arduino.

Kroger Co., a large nationwide grocery chain, maintains a customer reward system titled the “Kroger Plus” card. Customers who enroll in this system are entitled to discounts on products at Kroger stores and on gasoline. To earn discounts and other rewards, the shopper must use the “Kroger Plus” card at the time of checkout. The card has a bar code that identifies the customer. This system allows Kroger to determine customer buying patterns and to use the data for data mining. Using a Web search engine, search for “data mining” and “grocery.” In a one (1) page response, describe what types of information grocery stores collect that they can use for data mining purposes. Also, describe how grocery chains use data mining to improve performance.

Q2/ A teacher decided to sign students' papers with letters according to their degrees out of 100 if the degree >90 he gives “A", and if the degree >80 he gives “B", and if the degree <80 he gives pass . design decision table for the above system.

Orders for a stock trading system are coded as follows from left to right:1. The first character is 'B' for a "buy" order, 'S' for a "sell" order2. The number of shares to buy or sell3. The stock ticker symbol in all uppercase letters for a "buy" order or all lowercase letters for a "sell" order4. If the order is a "limit" order with a specific buy/sell price, the requested price is in pennies, otherwise the price should be omitted and the order will be a market order at the current asking price for the stock5. If the order is a "limit" order with an expiration time, the character 'T' followed by the number of minutes until the order expires should no longer be executedNote that the order code may only contain letters and numbers. (No comma, hyphen, etc)What would the code be to sell 8000 shares of Veteran Technology Solutions stock (ticker symbol: VTS) at the current market price?
