Child process to take the role of the number guesser

Reference no: EM13165678

You must implement a simple numbers guessing game. Write a program that allows for guessing a number. In reality, you would have somebody think of a number between 1 and 1000. Then you ask: "Is this number bigger than 512?" The person might answer: "Yes", in which case you add 256 (which is half of 512) to 512 -> 768. So, you ask: "Is this number bigger than 768?" The person might say "No". So you subtract 128 (which is half of 256) from 768, which is 640 etc. until you reach the number the person thought of. I hope you see the algorithm behind this game by now: it takes 10 questions to find any number between 1 and 2¹⁰-1.

Write a program in C that takes a number between 1 and 1024 as input on the command line, and then forks a child process to take the role of the number guesser. The parent process will take the role of the person who has the number, answering the questions as explained above. Both processes communicate using (unnamed) pipes. NOTE: the Child cannot "look" at or use the number input to the parent via the commandline.

You must print out all intermediate results, i.e. the "Yes" and "No", as well as the questions "Is the number ...".
