Calling a shell script from within C++ program

[Juggler]

Hi,
I have a shell script which takes three arguments, how can I call this
script from within a C++ program.
I am new to C++ programming and not sure how to accomplish this.
I tried using system() call but could make it work, must be doing
something wrong.
Appreciate any help in this regard.

Thanks,
Juggler

You have to consult your compiler/OS programming manual as to how to
invoke shell scripts using the 'system' function. You probably have to
specify what executable is to process your script, like

system("/bin/sh scriptname");

however, this is off-topic here, since C++ does not define how external
commands are executed via 'system' function.

Probably. Using the system() call is the only way to do it with
the standard C++ library.
Appreciate any help in this regard.

I would recommend asking on a platform-specific forum, as several
aspects of how system() works, and the other techniques you could
use to run the shell script, will depend on your operating system.
