Programming Assignment 1

In this assignment you will write a concurrent TCP server using fork(). The server will chose a random integer number between 1-100, and wait for the clients to send their guesses. The number of clients is pre-determined, say 2. But your code should be easily modified and be able to run for different number of clients. As enough number of clients send their guesses, the server finds out which one of the clients' guess is -closest- to its (server's) number. Finally, the server sends a greeting message to the winner client, and other clients should print a phrase indicating that they lost the competition.

Hints:

• First, try to understand how fork() works. It may confuse you sometimes.
• You will be dealing with integers again. So be sure to knoe how to use atoi() and sprintf() functions.
• The codes of the book [TCP/IP Sockets in C - Practical Guide for Programmers] are available through http://cs.ecs.baylor.edu/~donahoo/practical/CSockets/textcode.html. So you can download the [TCPEchoServer-Fork.c (without SIGCHLD) ] code and use it as a template for the assignment.
