Exercises

1. Create an example using GOTO that checks some variable for a value of 10 and then branches off to a NULL statement.
2. Create a WHILE loop to calculate a factorial. For example, 6! is 6 * 5 * 4 * 3 * 2 * 1. Use an initial value of 4! for testing. Make sure to issue the command SET SERVEROUTPUT ON and use DBMS_OUTPUT.
3. Create the same factorial calculation as Exercise 2, but use a simple LOOP statement instead.
