having trouble with reading in file word by word with link list

what i need this program to do is to read paragraphs like

"st blah blh test ere
se sit blha eere w"

and then it will reformat to

"st blah blh test ere se sit blha eere w" ....
i am having trouble try to read it word by word, since the link list
just go to the end, and never went to the second pointer to be able to
read the word blah

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <ctype.h>

char word[30];

} // end of if

} // end of while

If the program must be written in C, maybe you can ask in a newsgroup
devoted to that language.

If you are allowed to write it in C++, then investigate the fstream,
list, and string classes. You could probably write it in 10 lines of
code.

Doubt those, and you no longer*have anyone to discuss your doubts with,
nor any ability to discuss them.

Your code to too long...
If you are using C++,
try something like:

#include <iostream>
#include <fstream>
#include <algorithm>
#include <iterator>
#include <string>

int main()
{
std::ifstream file("test.txt");
std::copy(std::istream_iterator<std::string>(file) ,
std::istream_iterator<std::string>(),
std::ostream_iterator<std::string>(std::cout, " "));
return 0;
}
