I'm not sure just how portable this is, but:
int main (int argc, char **argv)
{
    // blah blah
}
"argc" will contain the number of arguments, and argv[] will contain the 
arguments themselves.  For example:
int main (int argc, char **argv)
{
int Count;
    cout << "Not-so-great demonstration of command-line switches" << endl;
    if (argc > 1)
    {
        for (Count = 1; Count <= argc; Count++)
        {
            cout << "Argument # " << Count << " is " << argv[Count] << endl;
        }
    }
    
    return 0;
}
Let's say this compiles to ARG.EXE.  If you type "ARG My Name Is Virgil", the 
program will display
Argument #1 is My
Argument #2 is Name
Argument #3 is Is
Argument #4 is Virgil
However, if you typed ARG "My Name Is Virgil" (with the quotes), it would 
display
Argument #1 is My Name Is Virgil.
Again, I am not completely sure how portable this is, but it worked here.
