Question on C++Design Pattern(Urgent)

Hi Experts,

I have to do the following.  I am given a object X, and I want to convert them to different objects based on the data provided in the X object.  All the objects( B, C etc. ) that I wanted to create are derived from a common class A as below.

class X{ }; // given to me by another interface

class A{ };

class B: public A{ };
class C: public A{ };
class D: public A{ };

As I was reading of design patterns and thought I could use Factory pattern.  Is it suitable for my problem?  If so, can you please give a simplified example.....

for example, Here is a quick example of what I wanted to do......

class EmployeeInfo{  // corresponds to X
string name;
string password;
string project;
string training;
string salary;
string manager_name;
string manager_id;
int numTeamMembers;
};

class Person { };  // corresponds to A

class Employee: public Person{  // corresponds to B
string name;
string password;
string training;
};

class Manager: public Person  // corresponds to C
{
string salary;
string manager_name;
string manager_id;
int numTeamMembers;
};

Given EmployeeInfo , I want to be able to create Employee, Manager objects...

Thanks a lot.
