Thanks Don!
Yes, I tried your code of post #2, which worked of course. Before my post I tried this version for format2.dat as I thought C takes input by line:
and this code:
both of which worked, but look very weird even to myself! Along with your version, I have three ways to do the same thing! These give me confusion that brought my post.
Book and tutorials I read use format1.dat as example to fill struct. From the manpage, it is not very clear to me without an exact example:
Handling stream (including parsing) in C is quite challenging to me, it is better now with fscanf(). Thanks a lot again!

Can someone tell me how to do this?
Just a thought that entered my mind when learning about structs.
First thought was:
struct one
{
struct two;
}
struct two
{
three;
}
one->two->three
would this be how you would access "three"? (1 Reply)
Hello,
I have a log file for the year, which contains lines starting with the data in the format of YYYY-MM-DD. I need to get all the lines that contain the DD being 04, how would I do this? I tried using grep "*-*04" but it didn't work.
Any quick one liners I should know about?
Thank you. (2 Replies)

fgets
FGETS(3P) POSIX Programmer's Manual FGETS(3P)PROLOG
This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the correspond-
ing Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.
NAME
fgets - get a string from a stream
SYNOPSIS
#include <stdio.h>
char *fgets(char *restrict s, int n, FILE *restrict stream);
DESCRIPTION
The fgets() function shall read bytes from stream into the array pointed to by s, until n-1 bytes are read, or a <newline> is read and
transferred to s, or an end-of-file condition is encountered. The string is then terminated with a null byte.
The fgets() function may mark the st_atime field of the file associated with stream for update. The st_atime field shall be marked for
update by the first successful execution of fgetc(), fgets(), fgetwc(), fgetws(), fread(), fscanf(), getc(), getchar(), gets(), or scanf()
using stream that returns data not supplied by a prior call to ungetc() or ungetwc().
RETURN VALUE
Upon successful completion, fgets() shall return s. If the stream is at end-of-file, the end-of-file indicator for the stream shall be set
and fgets() shall return a null pointer. If a read error occurs, the error indicator for the stream shall be set, fgets() shall return a
null pointer, and shall set errno to indicate the error.
ERRORS
Refer to fgetc().
The following sections are informative.
EXAMPLES
Reading Input
The following example uses fgets() to read each line of input. {LINE_MAX}, which defines the maximum size of the input line, is defined in
the <limits.h> header.
#include <stdio.h>
...
char line[LINE_MAX];
...
while (fgets(line, LINE_MAX, fp) != NULL) {
...
}
...
APPLICATION USAGE
None.
RATIONALE
None.
FUTURE DIRECTIONS
None.
