[QUOTE]We have to use other testing for primality, and I believe cse.avinash has explored using the Sieve of Eratosthenes, which I take it were also unsuccessful.

So , what's wrong with your program ? since we're not a psychic or in the mood of playing the"Guess what's wrong with my code" game, you have to tell us what exactly are you looking for.

Similar to echoserver, but this one handles multiple clients by forking the process.

This is a simple echo server that I've written while learning sockets programming. Compile the server and run it. You can connect to it using telnet like this: telnet localhost 1337 Disconnect the client by typing "/quit" without quotes.

When you compile your 'C' code, an object file is generated by the compiler. Such object files from each program(from the collection of programs) are build into a single binary(executabe) file by another program called linker.

[QUOTE]Can you tell me why use size_t and not int for orig_len and rep_len?[/QUOTE] Using size_t instead of just plain int or unsigned int makes your code more portable since the size of int types vary across platforms. Also the above standard functions expect their third argument to be of …

First of all, use code tags whenever you post any code.See that CODE thingy, click that and paste your well formatted code in between.
