Yet another epic story  /* There and back again a C tale by A.B.US.E. the great spammers...
* This program it's much better than the last one though still useless :)
* No matter that we repost a new code that does everything required. And guess
* what... It's obfuscated :P
* We don't have you exact deadline so... Post it asap. :)

We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty, and the pursuit of Happiness. ... hat whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, having its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness.
The Decleration of Independence - July 4th, 1776
We decided to post two codes one that uses realloc() and one that doesn't The obfuscated source code came from the one which doesn't use realloc(). Both programs work Some Remarks : What one should do here is to create a pointer that each of its members will hold memories to other pointers. Memory is allocated linearly (using malloc()) and thus the pointers can be used as arrays. Note that after each allocation we call memset() to initialize to 0 unless we immediately initialize our data by other means. Using stderr instead of stdout allows for unbuffered output (thus we use fprintf() instead of printf()). That's an explanation cause some people got really perplexed with this..  Have fun and ask any questions here Without realloc() : /* This code Provided to you by A.B.US.E. (a.k.a. Addicted to Binary USage Entertainment)
*
* It's been an hour of stupidity and laming around until we got this piece of garbage
* work. We, of course, obfuscated the code just to make sure you guys really try to
* write that thing down.
*
* For those who believe that this program is a useless piece of junk that all it does
* is irritating you... You're absolutely right...
*
* Kisses fly to all those who try hard to learn something out of these junks...
* Flames fly to all those who enforce people to work on such useless programs...
* Think differently...
*
* We will release the original code once your deadline is over... :-)
* Until then enjoy the summer :-)
