FieldValues = new vector<char*>();

I have the above FieldValues in a class as private member. How should
I deallocate the memory allocated by this vector. Also I am populating
the vector with <char*> dynamically allocated. I want make sure that
char* memory also deallocated when I destroy the instance of the
class.

Thanks for any help.

Thanks,

  I assume the vector is allocated on construction and therefore freed
on destruction. The 'FieldValues' variable will need to be checked if it
is NULL before the vector is used/deleted, and reset to NULL after the
vector has be deleted.
  Based on the vector containing dynamically allocated data I would
recommend a separate member function to delete the vector contents
before deleting the vector. In fact I would recommend you provide member
functions to handle/use the vector usage interfaces, in effect creating
a user specific container class to fit your requirements.
