Can't open file

[Darren]

Hi,
I'm having a problem openning a file. My code seems to work fine on the files that I have created, but won't open a file that my
instructor gave me. The file is a bunch of hex values(which really
shouldn't matter) and has a .dat extention. I thought that
possibly the extention was a problem, so I created a new .txt
file, then copied and pasted the data. My code would not open the new file either . Here is my code:

#include <stdlib.h>
#include <stdio.h>
void main(void)
{
FILE *fptr1;
char fname[]="Virtual_Machine.txt",c='y',ch,dum,out[20];
int i=0;
if((fptr1 =fopen(fname, "r"))==NULL)
{
printf("Cannot open %s.\n",fname);
exit(1);
}
while((c!='n')&&((ch=fgetc(fptr1))!=EOF))
{
printf("char is: %c \n",ch);
out[i]= ch;
printf("char is: %c \n",out[i]);
printf("CONTINUE?:\n");
c=getchar();
dum=getchar(); //flushes newline
}
fclose(fptr1);
}

Any insight would be greatly appreciated.
Thanks,
Darren

Instead of the non-informative

printf("Cannot open %s.\n",fname);

try using perror instead. It should tell you why the file can't be opened. Chances are that the program is looking in a different location that where the file is.

>void main(void)
void main is only valid if you're on a freestanding implementation. Since you're learning C, this is highly unlikely. Use one of these:

int main(void) /* No arguments */
int main(int argc, char **argv) /* Command line arguments */

And of course, return an integer value at the end.

Though the ANSI C standard no longer distinguishes text and binary files, for compatibility reasons change the fopen call to:

   fopen(fname,"rb")

What section, paragraph, and line did you read this from?
