Consider the following Boolean expressions. A && B
!A && !B
Which of the following best describes the relationship between values produced by expression I and expression II?
(A) Expression I and expression II evaluate to different values for all values of A and B.
(B) Expression and expression II evaluate to the same value for all values of A and B.
(C) Expression and expression II evaluate to the same value only when A and B are the same.
(D) Expression and expression Il evaluate to the same value only when A and B differ.
(E) Expression I and expression Il evaluate to the same value whenever A is true.

(D) Expression I and expression Il evaluate to the same value only when A and B differ.

Explanation:

Given

Required

Select the true statement

To do this, I will create the following case scenarios.

(a): and

i.e. true and true is true

------------------------------------------------------

------------------------------------------------------

So, we have:

So:

 and

Hence, options (B) and (E) are incorrect

(b): and

Solve each negation

So:

 and

Hence, option (c) is incorrect

(c): and

So:

  and

Case scenarios b and c implies that option (d) is correct because different values of A and B gives the same value of both expression which is false

This also implies that (a) is incorrect.

a variable of array type holds a reference of object

array are commonly used in computer program to organize data so that a related set of values

array are using zero base indexing it start with 0.

all component of array have same type, two different types doesn't use in single array

if array are store 10 quantities its index value varies from 0 to 9.

it stores 1st quantity value in index value 0 and this process will same till index value 9.
