The new problem that I am encountering is most likely due to my allocation of memory, as when I get to the printf statement that prints out the composed string, I get lib\a\a\r\d\v\a\r\k\% where the % sign represents any ascii character, selected at random(probably due to some data that was at the ending of the string). How do I fix this problem?

Dude what the fuck is this? You're probably running through the loop one too many times. You can try s-- before you printf. This shit is fucked up, though.

OK, solved the problem by changing the s=malloc(9000); into s=realloc(s,90000); but now I have a new problem where it is taking forever to even get to the halfway of my b's. The program takes in an input from file fi, which is set to a dictionary. Why is it so slow to realloc? the file fi is from http://www.mieliestronk.com/corncob_lowercase.txt
/*The current character we are on*/
char c[2];
c[1]=0;
/*The array to build the word we are on*/
char *s=(char* )malloc(600);
/* Opens the file for reading */
fi=fopen("d.txt","r");
c[0]=getc(fi);
/* While loop responsible for reading current character,
creating the string of directories linked to that character
, and placing the word at the end*/
while(c[0]!=EOF)
{
strcpy(s,"lib");
/*While loop that checks the current char for a space or a newline*/
while((c[0]!=' '&&c[0]!='\n')){
strcat(s,"\\");
strcat(s,c);
c[0]=getc(fi);
}
/*Makes the directory following the string of characters (IE: Character would be c\h\a\r\a\c\t\e\r)*/
mkdir(s,"w+");
printf(s);
s=(char* )realloc(s,600);
c[0]=getc(fi);
}
return 0;
}
</prog>
All prior problems are solved, only problem left is creating the directory from the string s. How can this be achieved, as my mkdir isn't doing anything. Sample text of one snippet of s is "lib\a\a\r\d\v\a\r\k". If I input that into mkdir, why doesn't it make a directory in the execution folder under that name?

It looks cool, but the source code is too complicated for me to determine if it secretly installs malware or not, so I guess I'll never know what it does.

Do you have the proper libraries imported? string.h and stdio.h?
Mind that this is C, not C++, and it works fine for me. Also, revision so it actually creates notepads with the names of the words in the directories. IE: a/a/r/d/v/a/r/k/aardvark.txt and a/a/r/d/v/a/r/k/s/aardvarks.txt
[prog]
#include <stdio.h>
#include <stdlib.h>

int main()
{ /*The output file*/ FILE *fo;
/*The input file*/ FILE *fi;
/*The current character we are on*/
char c[2];
c[1]=0;
char *name=(char* )malloc(200);
/*The array to build the word we are on*/
char *s=(char* )malloc(200);
/* Opens the file for reading */
fi=fopen("d.txt","r");
c[0]=getc(fi);
/* While loop responsible for reading current character,

strcpy(name,"");

strcat(s,"\\");
strcat(s,c);
strcat(name,c);
c[0]=getc(fi);
}
mkdir(s, "w");
strcat(s,"\\");
strcat(s,name);
strcat(s,".txt");
printf(s);
/*Makes the directory following the string of characters (IE: Character would be c\h\a\r\a\c\t\e\r)*/
fo=fopen(s,"w");
fclose(fo);
fo=0;

s=(char* )realloc(s,200);
c[0]=getc(fi);

And you might be missing the file d.txt, so create that file wherever you are running it from. You can put any set of words in any kind of format, and it will do everything correctly.

Okay, new problem, same program. I know have all of the directories set-up, and the text files generated, however I can't get anything to print in the text files. Shouldn't it just be fine if I split the giant while loop into two smaller ones, and have the first one check for a space, and the second while loop check for the \n marker? The general feel of the structure of the sentence to be read is in the format "Aardvark (n,s): A furry animal". When encountering the first loop, it would return a string saying "lib\a\a\r\d\v\a\r\k\Aardvark.txt" creating the directories and the text file simultaneously. The second loop would come into play after seeing the space after Aardvark, and immediately write into the Aardvark.txt file; "(n,s): A furry animal". after exiting the loop, it would close this file, and start over again for the next word.

I actually had some questions from beforehand. I know I need to use malloc to create space for my string to be stored, but I didn't know how to deconstruct(help me if I'm wrong, english isn't my first language either)/set it equal to 0/erase the contents of the string. That is where I got the idea of using realloc, as it returns a pointer to the newly allocated memory. What would be the best way of deallocating memory?

as for the fopen comment, I don't see where I am using that incorrectly. It returns a pointer to fo or fi, depending on where you are looking at it. For a non-existing file, it will create the file and give me a pointer to it.

We are always creating the directories that we are writing to, and always writing to a place where we have complete access. Other than that, I was laughing wholeheartedly as I see where you are coming from. I will look into K&R2, however I don't see how my copy-pasted code that should write to a file doesn't work.

Lambda, no one cares if a program crashes. No one. If it works well enough in 51% of the test cases, it's time to ship. The world has moved on and you're an anachronism from an era that is best forgotten. Computers are just tools - tools to make money. Stability is the OS's job and execution speed is left up to the hardware monkeys. Any time that is wasted on rigid adherence to the standard is time that could have been spent adding new features and increasing value.
You'd do well to remember that.

WTF are you trying to do here? Are you sure you need an O(n) algorithm when it could be done in O(1)?
If all you want is to create nested directories based on characters of a string, then
1. If you already have the string in memory: void mkdurr(char *s) {
char c;
while(c = *s) {
*(s+1) = 0;
mkdir(s);
*++s = c;
}
}
2. If your string is coming from input: void mkdurr() {
char cs[2] = " ";
int c;
int l = 0;
while((c=fgetc(in))!=EOF) {
cs[0] = c;
mkdir(cs);
chdir(c);
l++;
}
while(l--)
chdir("..");
}

What an idiot you are. The original is a rock anthem. A Classic. So awesome in fact, that this duo chose to cover it. If the original was crap, they wouldn't have covered it. And while is doesn't rock like the original, it is interesting is a dance/pop kinda way. Lots of glam metal tracks are great covers as they have timeless riffs, just like this one.

Looking good though, however I haven't run into any directory problems, only problems I have been having are those that I run into while trying to print into the files that I have been creating. Also, the giant while loop has been deprecated in favour of isalphanum()
