Calling a shell script from within C++ program

[tewari68]

Hi,
I am new to C++ programming. I have a shell script with takes three arguments, I have to call this shell script from within a C++ programme.
I tried using

system("/var/.../../bin/shellscript argument1 argument2 argument3");

however this doesn't seem to work.
Is there any other way I can call the script.
My OS is debian.

Thanks,
tewari.
