converting String to a type name

[saurabh.rbl]

Hello Friends,

The problem is that i get the names of the object type dynamically at
the run time as a string name to a function. Now this function is
suppose to create an object of the type name specified as the string
to the function. (Suppose we already have a class declared by that
name specified)

For e.g.

class ABC
{
};


int main() {
string k = "ABC" ;

// k * a = new k ; how to implement this??

return 0;
}

Thanks a lot,
Saurabh.

Use a std::map of std::string and a helper object that creates the
objects for each name. This assumes the types have a common base.
