        //do stuff
    break;
    case 2:
        //do other stuff
    break;
    case 3:
        return 0;  //Quit from within the case statement
    break;
    default:
        //if the user inputted something that wasn't a legal command
}

I don't know what the print() function is for, it seems like it just outputs the arguments the user entered, twice. And it will also print some garbage because you never declare the char 'op' to be equal to anything.
