Buy now Introduction Operating Systems have a need for extremely compact data structures, as often these need to be stored wholly in memory. Examples of this are free memory lists, page tables and disk space bitmaps. This  practical Case Study will refresh your knowledge of bit operations, necessary to manipulate such compact data structures. We will use a simple variant of the card game poker as the inspiration for our compact data structure. In this exercise, you will model a deck of playing cards as a bit 1eld. Only six bits are required to fully describe a card, two for the suit and four for the value. An extra bit as been added to the structure to encode the colour of the card. A second bit 1eld will be used to store the number of pairs contained in a hand. Read this section fully before attempting any of the exercises. These instructions contain some background information, the task to perform, sample code and some system documentation extract. 2 Structure of the bit 1elds 2...

Introduction For this assignment, you will perform basic ASCII file Input and Output. Your program will read a series of questions from an input file, present them to the user, get the user's responses to the questions, and write both the questions and the responses to an output file. Specifications You program will begin by prompting the user to enter two filenames. The first filename will be the input file that contains the questions. The second filename will be the output file where the questions and responses will be written. Once the filenames are known, the program will open the two files, one for input and one for output. Your program will then enter a loop which will read each question from the input file, print the question to the console, and get the user's response to the question from the console. It will then write both the question and response to the output file. Your program will continue to do this until there are no more questions to be read from the input fil...
