read from a file... Fortran or C

Hi there,
I'm trying to read data from a file that looks like this:
Into a 2D-array in either C or Fortran (preferably Fortran, and F77).
The file has 128 numbers on each row (space separated) and is 128 lines deep, so I want a 128 x 128 2D array.
Anyone have any ideas? I have made a little progress, but I don't know enough about fgets (in C) or the READ command (in F77), or about string manipulation to get my head around it.

Reply:
fgets will read a long of N characters UNTIL it reaches a newline (\n). IE. this will strip one line at a time from your file for the command: fgets( string, 256, fp ); assuming no lines are greater than 256 characters long.
After that, it's just a matter of picking the numbers off the front of the string and finding the next space. Pointers are your friends.
