Isn't this obvious from the code I presented in post #2 in this thread where the fscanf() format string "%s %lf %lf %lf" was able to read four values from one or two lines from format1.dat and able to read four values from four or five lines from format2.dat? And the format string "%s%lf%lf%lf" would have produced the same results but isn't as easy for some people to read.
Have you read the man page for fscanf() recently. Look at it closely. (Characters that are classified as space characters by isspace() are ignored between strings being matched against conversion specifications other than for conversions with a conversion specifier [, c, C, or n.)
Did you try your fscanf() calls in a program? Or, are you just looking at the statements and wondering what they would do? (You could have easily answered this question yourself by putting your code in a program and trying it. And, you could probably have had the results in less time than it took you to type in your post.)

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)

FGETS(3) BSD Library Functions Manual FGETS(3)
NAME
fgets, gets -- get a line from a stream
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <stdio.h>
char *
fgets(char * restrict str, int size, FILE * restrict stream);
char *
gets(char *str);
DESCRIPTION
The fgets() function reads at most one less than the number of characters specified by size from the given stream and stores them in the
string str. Reading stops when a newline character is found, at end-of-file or error. The newline, if any, is retained. If any characters
are read and there is no error, a '
