File Handling -Read write and edit a file

Hi guys im trying to get a program to read a file and copy its contents to another file so far I seem to be having a problem.
The file is only writing one letter, "X" in this case
Im just wondering what my problem is here?
the file im testing it on is just a massive text document, so there dhould be more than one letter comming out

Code:

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>

int main ( int argc, char *argv[] )
{
    if ( argc != 2 )
    {

        printf( "usage: %s filename", argv[0] );
    }
    else
    {

        FILE *file = fopen( argv[1], "r" );


        if ( file == 0 )
        {
            printf( "Could not open file\n" );
        }
        else
        {
            int x;

            while  ( ( x = fgetc( file ) ) != EOF )
            {
                FILE *outf;
	//if (isspace(x)&&isspace(x-1)
	//remove space
	//else
	outf = fopen("test.txt","w");


	fprintf(outf,"%c");
    fclose(outf);

            }

        }

        fclose( file );
    }
}

Eventually im going to use this program to tidy up a text document with float values, that sounds confusing as I type it, but its just a text file with numeric data on it but its very messed up as it looks something like this

Code:

121.2       12.12 121.21         1.212 
1.12 121 121 1        1.212    12.12      121.2 12
ect....

What I want to do is tidy it up so that there is only one space between each value and hopefully start a new line after every 10 numbers.

Code:

fprintf(outf,"%c");

You're only printing a single character here, and what's even worse, you haven't even supplied an address to print so the value is going to be some random value from the stack.

But I thought once inside the while loop until it gets to the EOF it will keep adding to the file?
Also there is no 'X' in my text file?
How do I correct this?

Yes that is correct (I missed it because of the horrible indentation you use).

> Also there is no 'X' in my text file?
The "%c" specifier in the printf family requires you to supply a char parameter (and you haven't). What exactly do you expect to print when you haven't told fprintf which variable to print?
