Instantiating an object of the cmd line arg type

[Madhusudhanan Chandrasekaran]

Hi,

Is it possible for me to instantiate an object of the type
which is passed in as cmd line argument. I know this can be done
in Java/Python having reflections. Is there any c++ way of doing this
either with rtti or some other hack.

Thanks,
Madhu

Command line arguments in C++ are simple C-style strings.

You can parse the command line arguments, find out what kind of object
they specify, and instantiate that kind of object.

There's no built-in feature that helps directly with that.
