I think you can use first program argument. It is a string containing path of executable. You can access it by usingint main(int argc, char *args[]) instead of int main(). The args[0] contains what you need. Just take a substring of it, to get the path and concatenate it with your filename.

You could use an absolute path to your file:

FILE* fp = fopen("c:\\your_dir\\your_file.txt", "r");
if(fp) {
   // do something
   fclose(fp);
}

or a relative path, assuming your file is located in c:/etc and your executable is located in c:/etc/executables:

FILE* fp = fopen("..\\your_file.txt", "r");
if(fp) {
   // do something
   fclose(fp);
}
