System()

[nnandini8]

Hello Friends,
I am trying to write a program that takes a command
line arguement and a input file.
I know that I can do this using system() but I am not able to
understand how to pass the file.

ex: "dnaml" is a command line arguement.
This asks for a input file known as "infile"

so how do i pass it in system() function

I tried system("dnaml infile")
which is of no use.

Any help is greatly appreciated

Cheers
Nandini

I'm afraid you're going to have to be more clear on the problem if you
expect an answer.

Sorry
Here is my problem.

when I type "dnaml" in command line and hit enter it asks for the file
name "infile". Now I need to pass "infile" when "dnaml" command
executes how do I do that

Any help is greatly appreciated

system("echo infile | dnam1"); will work if dnam1 does not use any advanced
console techniques to read its input string.

Also, all of this stuff is off-topic except system() itself, so you will get
better results on a newsgroup covering your command line system (CMD.EXE,
bash, etc.).
