Well, you COULD... ;) With C, though, you have to use argv and argc. :)
Let's change it to do something like what you wanted:
Change the first part to look like this instead:
#include <stdio.h>
#include <ctype.h>
/* Make this how long you want the lines to be */
#define MAX_LINE_LENGTH 80
int main(int argc, char *argv[])
{
FILE *fp1;
FILE *fp2;
char c;
char c2;
int counter;
int endofline;
if (argc != 3)
{
printf("Usage: %s <input filename> <output filename>",
argv[0]);
return -1;
}
if ((fp1 = fopen(argv[1], "r")) == NULL)
{
puts("Damn, couldn't open input file!");
return -1;
}
if ((fp2 = fopen(argv[2], "w")) == NULL)
{
puts("Damn, couldn't open output file!");
return -1;
}
----------------------------
That way, you can specify the input filename and the output filename. ;)
Looks like Declan's gonna be learning himself some C here. :D
Also...

What I'd recommend there is something similar... The \t are tabs, of
course, and you're just outputting them to the screen... So you're
outputting a newline, 12 tabs, then another newline, and then the string
{11}... I don't think that's what you're intending. :) I'm not quite sure
what you're intending, but "puts" is a VERY simple function... It simply
puts whatever is in there to the output stream (fp2, the second file
pointer, in this case). You're probably looking for something more like
printf, which allows you to output all sorts of stuff in a nicely formatted
manner...
