Passing arguments in system()

[Chris]

I am having trouble with system() in a c++ application I am trying to
link to a robotic arm:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
string movement= "move arm right";
system("C:\\Program Files\\ATTLABS\\NATURAL VOICES\\VoiceCommand /
text= movement /voice=\"AT&T Natural Language Mike\"");
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I am trying to use system() to start an AT&T app (VoiceCommand) with
the arguments /text="" and /voice="".

Could someone give me a heads up of what a better function or way to
use system() may be?

Thank you very much for your time.

Build up the command externally, and pass the result to system().

std:stringstream ss;
ss << "C:\\Program Files\\ATTLABS\\NATURAL VOICES\\VoiceCommand"
<< " /text=\"move arm right\""
<< /voice=\"AT&T Natural Language Mike\"";
system(ss.str().c_str());

Note that "movement" is taken here literally. It is not the string variable you declared earlier.
As said already in the other respons, it may be better to construct the string
in one or more lines of code and than pass it to system ().
In that way you can also print the string for debugging to verify what is passed to system ().
