How stupid to use the scanf format for printf!------Thanks, Corona!
I got it now:

Also, you are giving printf all the same arguments too. scanf needs &i because scanf needs i's location, not its contents -- but printf needs its contents, not its location!
If print string, use the address of the string array(cf: string+5); if print the char of the string, use the subscription (string[5]) explicitly.

What is the output of the following program considering an x86 based parameter passing sequence where stack grows towards lower memory addresses and that arguments are evaluated from right to left:
int i=10;
int f1()
{
static int i = 15;
printf("f1:%d ", i);
return i--;
}

Hi,
I have just completed my first script (:D) and now i just need to format it with printf.
This is what I have:

Target file contains short text (never more than 1 line) and filenames.
The format is, e.g.,:
TEXT1
filename1
TEXT2
TEXT3
filename3dddd
filename3dddd
TEXT4
filename4
TEXT5
filename5dddd
filename5dddd
filename5
where dddd is a random 4-digit whole number.
Desired output: (4 Replies)

sprintf
printf(3int)printf(3int)Name
printf, fprintf, sprintf - print formatted output
Syntax
#include <stdio.h>
int printf ( format [, arg ] ... )
char *format;
int fprintf ( stream, format [, arg ] ... )
FILE *stream;
char *format;
int sprintf ( s, format [, arg ] ... )
char *s, *format;
Description
The international functions and are similar to the standard I/O functions. The difference is that the international functions allow you to
use the %digit$ conversion character in place of the % character you use in the standard I/O functions. The digit is a decimal digit n from
1 to 9. The international functions apply conversions to the n th argument in the argument list, rather than to the next unused argument.
You can use the % conversion character in the international functions. However, you cannot mix the % conversion character with the %digit$
conversion character in a single call.
You can indicate a field width or precision by an asterisk (*) instead of a digit string in format strings containing the % conversion
character. If you use an asterisk, you can supply an integer arg that specifies the field width or precision. In format strings containing
the %digit$ conversion character, you can indicate field width or precision by the sequence *digit$. You use a decimal digit from 1 to 9
to indicate which argument contains an integer that specifies the field width or precision.
The conversion characters and their meanings are identical to
You must use each digit argument at least once.
In all cases, the radix character uses is defined by the last successful call to category If category has not been called successfully or
if the radix character is undefined, the radix character defaults to a period (.).
International Environment
LC_NUMERIC If this environment is set and valid, uses the international language database named in the definition to determine radix
character rules.
LANG If this environment variable is set and valid uses the international language database named in the definition to determine
collation and character classification rules. If is defined, its definition supercedes the definition of LANG.
Examples
The following example illustrates using an argument to specify field width:
printf ("%1$d:%2$.*3$d:%4$.*3$d
",
hour, min, precision, sec);
The format string *3$ indicates that the third argument, which is named precision, contains the integer field width specification.
To print the language independent date and time format use the following statement:
printf (format, weekday, month, day, hour, min);
For American use, format could be a pointer to the following string:
"%1$s, %2$s %3$d, %4$d:%5$.2d
"
This string gives the following date format:
Sunday, July 3, 10:02
For use in a German environment, format could be a pointer to the following string:
"%1$s, %3$d. %2$s, %4$d:%5$.2d
"
This string gives the following date format:
Sonntag, 3. Juli, 10:02
Return Values
and return zero for success and EOF for failure. The subroutine returns its first argument for success and EOF for failure.
In the System V and POSIX environments, and return the number of characters transmitted for success. The function ignores the null termi-
nator ( ) when calculating the number of characters transmitted. If an output error occurs, these routines return a negative value.
