Pointers and nested structures

Hello,
I am really scrwed up with the following stuff:

struct employee
{
char* employee_name;
};

struct department
{
char* department_name;
struct employee* emp; //Collection of all employees in a
department
};

In main(), I wrote
struct department* company;

I want to first enter the name of department and
then names of employees in that department. I tried with pointers but I
must hv messed up somewhere n getting segmentation faults. Tried using
array representation e.g. company[i].emp[j].employee_name . This also
failed. I used new operator but it didn't help. Please tell me how to
deal such thing in pointers.

Thanks!!!
