Q31.

What is the purpose of using conventional 'if' statements in programming?

To create long statements with multiple conditions

To allow for more flexible conditional statements

To support complex conditions in 'switch' blocks

To use hardcoded constants in 'switch' blocks

Discuss

Answer: (b).To allow for more flexible conditional statements Explanation:The reason that programmers sometimes must use ‘if’ statements is that they allow for more flexible conditional statements.

Q32.

What is the difference between a 'switch' block and a sequence of 'else-if' statements?

'Switch' blocks support complex conditions, while 'else-if' statements use hardcoded constants

'Switch' blocks allow for more flexible conditional statements, while 'else-if' statements don't

'Switch' blocks can have several conditions leading to the same code block, while 'else-if' statements link each condition to just one code block

'Switch' blocks add additional "alternate blocks," while 'else-if' statements don't

Discuss

Answer: (c).'Switch' blocks can have several conditions leading to the same code block, while 'else-if' statements link each condition to just one code block Explanation:Unlike ‘switch’ blocks where several conditions can lead to the same code block, with these kinds of ‘else-if’ blocks each condition is linked to just one code block.

Q33.

What are compound conditionals?

Conditional statements based on a single condition

Conditional statements based on more than one condition

Conditional statements based on hard-coded constants

Conditional statements that don't use logical operators

Discuss

Answer: (b).Conditional statements based on more than one condition Explanation:Compound conditionals are conditional statements based on more than just a single condition.

Q34.

What is the challenge faced by reversers when deciphering compound conditionals?

The low-level code generated for a combination of logical checks is easy to decipher

The high-level code generated for a combination of logical checks is easy to decipher

The low-level code generated for a combination of logical checks is not always easy to decipher

The high-level code generated for a combination of logical checks is not always easy to decipher

Discuss

Answer: (c).The low-level code generated for a combination of logical checks is not always easy to decipher Explanation:Reversers face the challenge of deciphering the low-level code generated for a combination of logical checks, which is not always easy to decipher.

Q35.

What is the purpose of using compound conditionals in programs?

To make programs simpler and more efficient

To allow for flexible conditional statements

To avoid the use of logical operators

To allow for complex hard-coded constants

Discuss

Answer: (b).To allow for flexible conditional statements Explanation:The purpose of using compound conditionals is to allow for more than just a single condition in conditional statements and to allow for flexible conditional statements.

Q36.

What are logical operators?

Special characters used for combining more than one logical statements

Special characters used for separating more than one logical statements

Special characters used for combining more than one conditional statements

Special characters used for separating more than one conditional statements

Discuss

Answer: (a).Special characters used for combining more than one logical statements Explanation:Logical operators are special characters used for combining more than one logical statements in a single conditional statement.

Q37.

What are the two most common logical operators used for combining multiple conditions?

AND and OR

IF and ELSE

NOT and XOR

ADD and SUB

Discuss

Answer: (a).AND and OR Explanation:The two most common logical operators for combining more than one logical statement are AND and OR.

Q38.

How is a compound conditional with the AND operator detected in assembly language?

Two consecutive conditions that unconditionally branch to the same address

Two consecutive conditions that conditionally branch to different addresses

Two consecutive conditions that conditionally branch to the same address

Two consecutive conditions that unconditionally branch to different addresses

Discuss

Answer: (c).Two consecutive conditions that conditionally branch to the same address Explanation:A compound conditional with the AND operator is detected in assembly language as two consecutive conditions that conditionally branch to the same address.

Q39.

What is the purpose of the conditional code block in a compound conditional with the AND operator?

It is executed if neither branch is taken

It is executed if both branches are taken

It is executed if the first branch is taken

It is executed if the second branch is taken

Discuss

Answer: (a).It is executed if neither branch is taken Explanation:The conditional code block in a compound conditional with the AND operator is executed if neither branch is taken.

Q40.

What are the two most common logical operators used for constructing compound conditionals in high-level languages?

AND and NOT

OR and NOT

AND and OR

XOR and NOR

Discuss

Answer: (c).AND and OR Explanation:The two most common operators for combining more than one logical statements are AND and OR.
