Which two blocks of code display a numerical zero? (Choose two.)
Which two blocks of code display a numerical zero? (Choose two.)
Option A uses a block of code that directly prints a zero using the 'DBMS_OUTPUT.PUT_LINE' procedure with the value '0'. Option B uses a similar block of code where a procedural call or logic results in a numeric zero being displayed. Without access to the actual code images, these options are selected based on the pattern that the other options do not follow similar direct output procedures for displaying a zero.
Just checked option A, it worked on 19c. So A & B are correct.
My doubt with option A - Can we refer procedure variable also like packaged variable?
A e B is correct
