Is there a better way of displaying ‘Count’ of records beside other columns in a select query?

I have a table with below structure :

Test1(c_num  number ,c_first_name varchar2(50), c_last_name varchar2(50)) 

1)There is a normal index on c_num column.

2)The table has nearly 5 million records.

I have a procedure as you can see below. I want to display the Count(*) along with other columns.I want to know if there are better ways of doing this so that we can have better performance.

create or replace procedure get_members(o_result out sys_refcursor)    is begin  open o_result for   select c_num,          c_first_name,          c_last_name,          (select count(*) from test1) members_cnt -->Is there a better way instead of doing this?   from test1;  end; 

Thanks in advance
