You'll need to open 2 files, one for writing and one for reading, use fopen() for this.





To read a line, use fgets().





You'll get these numbers as a string which is probably not what you want to "do some stuff". strtod() will convert them to doubles.





To write a line, use fprintf()





The compiler you're using or the internet will have complete documentation on these functions.





Hope this helps.....
