• True

• False

• Undefined

Multiple Choice

What is the output of code snippet?

• x is greater than y

• no output

• x

• y

Multiple Choice

What is the output of the code snippet?

• x is greater than y

• no output

• x

• y

Multiple Choice

What is the value of the variable largest after performing the code snippet?

• 0

• 100

• 45

• No value

Multiple Choice

What is the value of the variable largest after performing the code snippet?

• 0

• 100

• 45

• No value

Multiple Choice

If x is 5 and y is 10, what is the output of the code snippet?

• $

• #

• No output

Multiple Choice

If x is 5 and y is 1, what is the output of the code snippet?

Multiple Choice

if the value of final score is 100, what is the output of the code snippet?

• You got A!

• You got B!

• You got C!

• You got D!

• You got F!

Multiple Choice

if the value of final score is 59, what is the output of the code snippet?

• You got A!

• You got B!

• You got C!

• You got D!

• You got F!

Multiple Choice

What is the output of the switch statement?

• code path executed for value 0

• code path executed for value 2

• code path executed for value 3

• code path executed for default path

Multiple Choice

What is the output of the switch statement?

• code path executed for value 0

• code path executed for value 2

• code path executed for value 3

• code path executed for default path

• None of the choices

​In this example, the correct output is

​

​code path executed for value 2

code path executed for value 3

​

​Why?

​

​Case 2 does not have a break statement. Thus, it will continue on the next case.
