I want to read records from a file and store them into an array,
but the problem is I don't know how many records I'll read,
so I don't know how to declare the array.

I tried this:
  struct sRec {
    char sStdNo[9];
    int sMarks[3];
    float sFinal;
  };
  struct sRec studentRec[];

but there is a warning (no warning in Visual C or Turbo C, but a warning in
UNIX C).

Please give me some suggestion

Thanks,

C doesn't have arbitrary sized arrays.  Either use a linked list,
or a dynamically sized array with storage generated as needed with
realloc(); which you use depends on what you're planning to do with
the data, and how much the data varies over the life of the program.
