You can eliminate the "continue" in your example if you write it like this:

    if ( cmd == "^" )
        break;
    else if ( cmd == "+" )
        Add(stack);
    else if ( cmd == "-" )
        Sub(stack);
    else
        stack.push_back(1);


As for the break, it could just as easily be a 'return' like in the haskell 
code, if you didn't want to print "exit" or if you brought the loop into its 
own function.
