Yours was one of the fairly rare cases where one could determine the
likely problem just from the description . . .

Nitpick:  main must return int according to ANSI C 5.1.2.2.1.

As I suspected, here's the problem.  You're writing binary data to the
file (can't get much more binary than the internal representation of
doubles), but you're opening the file in text mode.  Change this line to 

    fp = fopen("ran.bin", "rb");

and your program should work fine.
