Answer 1

Arun has shown you an example using PL/SQL. If you want to do something similar in other languages you have to use their style of variable declaration e.g. if you wanted to do it through SQL*Plus, you need to declare the variable within SQL*Plus itself and bind that into your calls e.g.
SQL> create procedure p_inout (p_val in out number) is
  2  begin
  3    p_val := p_val*10;
  4  end;
  5  /
Procedure created.
SQL> var mynum number
SQL> exec :mynum := 10;
PL/SQL procedure successfully completed.
SQL> print mynum
     MYNUM
        10
SQL> exec p_inout(:mynum);
PL/SQL procedure successfully completed.
SQL> print mynum
     MYNUM
       100
