    Well, you'd probably start by opening the file, using fscanf to read the number or numbers you want into the desired variables. Come back with some code; we'd be happy to help you further.

  • Or even better, open the file and read each line into a buffer and than use strtof to step through the buffer picking out value (or sscanf updating the pointer position following each conversion)
