You see that code I asked you to copy-paste into your shell, a few posts back, there?

Copy-paste it into your shell, please. Don't type it. Copy-paste.

Your code wasn't actually giving wrong numbers for 1234512345?

When a program doesn't work as you expect, post the literal program. It works for 1234512345, it works for 1000000000, but it won't work for anything bigger than 4 billion because you run out of room in an unsigned integer. If you dont't post what you actually did, how am I supposed to guess what went wrong?

To print longer integers, you have to start using 64-bit integer types like int64_t from stdint.h and I don't know of any portable way to print those.

When to define functions in C?

Hey everyone.

paste

PASTE(1)						    BSD General Commands Manual 						  PASTE(1)

NAME

     paste -- merge corresponding or subsequent lines of files

SYNOPSIS

     paste [-s] [-d list] file ...

DESCRIPTION

     The paste utility concatenates the corresponding lines of the given input files, replacing all but the last file's newline characters with a
     single tab character, and writes the resulting lines to standard output.  If end-of-file is reached on an input file while other input files
     still contain data, the file is treated as if it were an endless source of empty lines.

     The options are as follows:

     -d list	 Use one or more of the provided characters to replace the newline characters instead of the default tab.  The characters in list
		 are used circularly, i.e., when list is exhausted the first character from list is reused.  This continues until a line from the
		 last input file (in default operation) or the last line in each file (using the -s option) is displayed, at which time paste
		 begins selecting characters from the beginning of list again.

		 The following special characters can also be used in list:

		 
    newline character
		 	    tab character
		 \    backslash character
		     Empty string (not a null character).

		 Any other character preceded by a backslash is equivalent to the character itself.

     -s 	 Concatenate all of the lines of each separate input file in command line order.  The newline character of every line except the
		 last line in each input file is replaced with the tab character, unless otherwise specified by the -d option.

     If '-' is specified for one or more of the input files, the standard input is used; standard input is read one line at a time, circularly,
     for each instance of '-'.

EXIT STATUS

     The paste utility exits 0 on success, and >0 if an error occurs.

EXAMPLES

     List the files in the current directory in three columns:

	   ls | paste - - -

     Combine pairs of lines from a file into single lines:

	   paste -s -d '	
' myfile

     Number the lines in a file, similar to nl(1):

	   sed = myfile | paste -s -d '	
' - -

     Create a colon-separated list of directories named bin, suitable for use in the PATH environment variable:

	   find / -name bin -type d | paste -s -d : -

SEE ALSO

     cut(1), lam(1)

STANDARDS

     The paste utility is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.

HISTORY

     A paste command appeared in Version 32V AT&T UNIX.
