Chapter 8 Exam Review

What type of loop would you use if you want a numeric index and know how many times the loop should run?

• "for" loop

• "while" loop

• infinite loop

• "numeric" loop

When a "for" loop ends, where does the program flow continue?

• At the first non-indented statement after the loop body

• Program flow resumes at the statement directly above the "for" keyword

• The entire program halts immediately when the loop is done

• for() loops, by design, will never end

In the code, which statement(s) are part of the "for" loop body?

• LINE 3 only

• LINES 2 and 3 only

• LINE 1 and 4 only

• LINES 1, 2, and 3 only

How many times will the loop body run in the code below? data = "count" for x in data: print(x)

• 5

• 6

• 1

• 0

What value is stored in the "total" variable after the following code runs? total = 0 for i in range(1,4): total = total + i

• 6

• 0

• 5

• 10

What will be the output of the following "for" loop?

• 0 3 6 9 12 15 18 21 24 27

• 1 3 6 9 12 15 18 21 24 27 30

• 0 9 18 27

• 0 3 6 9

What will be displayed on the screen when the following code is run?

• c#o#u#n#t

• count

• #t

• #####

What kind of expression must be used as part of the "while" loop statement?

• logical expression

• mathematical expression

• assignment expression

• All of these will work

Which of the following best describes how many times the statements in the body of a "while" loop will run?

• 0, 1 or more times depending on the logical expression of the "while" statement

• At least once

• A maximum of 10 times no matter what

• An infinite number of times until a "continue" statement is reached

How do you identify the statements that belong in the body of a "while" loop?

• Indent them an equal number of spaces to the right of the "while" keyword

• End each loop body statement with a colon (:)

• All statements between the "while" and "endwhile" keywords are part of the loop body

• Only the first statement after the "while" statement is ever part of the loop body
