want to use output of c programme in expect
hi
i am having a c code which gives the output of my password in text format

i.e when i run my c code which which gives the password asfollows====>>>>>>
$./passwdprogram ======>>>>>>abc@123(this is the output)


now i have an expect script to remotely ssh which uses the password set in programme and works fine
if given in clear text format as follows
==========================================
#!/usr/bin/expect -f

set argu [lindex $argv 0]
set argg [lindex $argv 1]
set password "abc@123" ================here i want to change


spawn ssh user@<ip adress > sh portalhits $argu $argg
expect "^password:"
send "$password\r"
interact
==========================================
I want to use this in the following way

#!/usr/bin/expect -f

set argu [lindex $argv 0]
set argg [lindex $argv 1]
set password "./passwordprogramme" (in c) ================here i want to change


spawn ssh user@<ip adress> sh portalhits $argu $argg
expect "^password:"
send "$password\r"
interact
============================
so i want to figure that is there any way by which i can set the variable password with the output of the c code(./passwordprogramme) programme

can we do this by system() command .


Thanx Smilie

catod

CATOD(1)						      General Commands Manual							  CATOD(1)

NAME

       catod - To convert the text format of a dictionary to binary
	       format.

SYNOPSIS

       catod  [-s maxword ] [-R] [-r] [-e] [-S] [-U]
	      [-P dicpasswd ]	 [-p frepasswd ]
	      [-h cixingfile ] outfilename

DEFAULT PATH

       /usr/local/bin/cWnn4/catod

DESCRIPTION

       This command converts a dictionary from text format into binary format.

       outfilename  is	the  name  of the binary format dictionary.  If outfilename is not given, the output will be passed to the standard output
       device(stdout).

       The input file may be piped in by using the "<" command.  For example,
	    catod  basic.dic  <  basic.u
       "basic.dic" here is the output binary format dictionary, while the "basic.u" is the input text format dictionary.

       If the input text dictionary is not given, the input will be taken from the standard input(stdin).  To end the input  via  standard  input,
       press ^D.

OPTIONS

       -s     maxword
	      To specify the maximum number of words.  Default is 70000.

       -R     To create a dictionary for both forward and reverse conversion.  (Default).

       -r     To create a reverse format dictionary only for reverse conversion.

       -e     If  the  Hanzi  inside  the  text  dictionary  contains  characters such as space and tab, they will be compacted to special format.
	      (Default).

       -S     To create a static dictionary.

       -U     To create a dynamic dictionary.

       -P     dicpasswd
	      To specify the password for the dictionary.
	      If "-N" is used instead, the password of the dictionary will be set to "*".

       -p     frepasswd
	      To specify the password for the usage frequency file.
	      If "-n" is used instead, the password of the frequency file will be set to "*".

       -h     cixingfile
	      To specify the Cixing definition file.

NOTE

       1.     The parts in [ ] are options.  They may be omitted.

       2.     The Pinyin and Zhuyin dictionary has the same format.

       3.     For details of the dictionary structure, refer to cWnn manual.
