Write a program in PL/SQL to show the uses of implicit cursor without using any attribute

DECLARE
    emp_first_name VARCHAR2(35);
    emp_last_name  VARCHAR2(35);
	zemp_id NUMBER:=&employee_id;
BEGIN
    SELECT first_name,
           last_name
    INTO   emp_first_name, emp_last_name
    FROM   employees
    WHERE  employee_id = zemp_id;

    dbms_output.Put_line ('Employee name: '
                          || emp_first_name
                          ||' '
                          ||emp_last_name);
EXCEPTION
    WHEN no_data_found THEN
      dbms_output.Put_line ('There is no employee with the ID '||to_char(zemp_id));
END; 
/ 

Sample Output:

SQL> /
Enter value for employee_id: 485
old   4:        zemp_id NUMBER:=&employee_id;
new   4:        zemp_id NUMBER:=485;
There is no employee with the ID 485

PL/SQL procedure successfully completed.

SQL> /
Enter value for employee_id: 147
old   4:        zemp_id NUMBER:=&employee_id;
new   4:        zemp_id NUMBER:=147;
Employee name: Alberto Errazuriz

PL/SQL procedure successfully completed.

PL/SQL opens an implicit cursor  with the SELECT INTO statement and after the SELECT INTO
statement completes, closes the implicit cursor.
