Hi, I am having trouble adding a text file to my project. I have written a program in C to read from a file. I have added the file name untitled but
the program says that the file does not exist and can't be open.
When I looked at the project folder the file is there and when I look at targets it is also there. Thanks for your help. Here is the code.
I have copied it to the unix terminal and it worked just fine.

SEEK-CUR Set position to current location plus offset

printf("unable to open %s!\n\n",INFILE);
//perror(INFILE); /* display las error message */
exit(1);
}
/* Read all lines from the file and look for the start that indicates the next line is a title.

/* Revisti all titles by getting the saved offset and positoning the
file pointer from the beginning of the file */
for(c=0; offset[c] >=0; c++) /* Walk through the file address position fiel at addres saved and the nprintf */
{
fseek(fp,offset[c], SEEK_SET); /* seek_set long it. fseek postion the file pointer where ever location is given */
fgets(iline,81,fp); /* then read the title line */
printf("%3d. %s", c +1, iline); /* then print it*/
}/* end for loop */
// insert code here...
printf("Hello, World!\n");
return 0;
