Review lesson 7.6.3

What is the output when using the AND operator with two inputs, where the first input is true and the second input is false?

• True

• False

• 1

• 0

If a program uses the OR operator and both inputs are false, what will

be the output?

• True

• False

• 0

• 1

Which of the following conditions will return true when using the AND operator with three inputs: A, B, and C?

• A is false, B is true, C is true

• A is true, B is false, C is true

• A is true, B is true, C is true

• A is false, B is false, C is true

In a program using the OR operator, if one of the inputs is false and the other is true, what will the result be?

• True

• False

• 0

• 1

What will happen if you combine the AND and NOT operators in a single expression?

• The result will always be true

• The result will always be false

• The NOT operator will invert the result of the AND operation

• The AND operator will invert the result of the NOT operation

Which Boolean operator is used in logic gates that are implemented as "if-else" statements in programming?

• AND

• OR

• NOT

• All of the above

If the program checks the condition (NOT A AND B) and button A is pressed (true), and button B is not pressed (false), what will be the result?

• True

• False

• 0

• 1

In a flowchart with a decision to check if “either button A or button B is pressed” using the OR operator, what will the output be if both buttons are not pressed?

• True

• False

• 0

• 1

What will happen if the NOT operator is applied to the result of an AND operation between two inputs?

• It will negate the entire result of the AND operation

• It will negate the first input only

• It will negate the second input only

• It will have no effect on the result

How does a sub-routine improve program efficiency in terms of repeated code?

• By allowing the program to run faster

• By organizing and simplifying code that may be reused multiple times

• By avoiding the use of variables

• By reducing the number of decisions in the program
