Point out the error in the program?

int main()
    FILE *fp;
    fp=fopen("trial", "r");
    fseek(fp, "20", SEEK_SET);
    return 0;
Error: unrecognised Keyword SEEK_SET
Error: fseek() long offset value
No error
None of above
Answer: Option
Instead of "20" use 20L since fseek() need a long offset value.

seek_set = Cursor moves to first letter of the file .
seek_end = Cursor moves to last letter of the file.
seek_cur = Cursor starts when ever we accessed last world.
