Hi there,

Do you mean command line arguments?

You can access those by doing:

int main( int argc, char* argv[]) // command line arguments passed to main
{
    if (argc >1)  //if more arguments than only the filename
    {
        for (int i=0; i<argc; i++) std::cout << argv[i] <<std::endl;  //print them
    }
}

Hope that helps,

All the best,
NwN
