The following algorithm prints the sum of the 5 consecutive integers starting at 1: Reference Line Program Statements Line 1 ……………….. LET sum = 0 Line 2 ……………….. LET num = 1 Line 3 ……………….. DO WHILE num

Write the Line number from the above program that best applies to each of the statements below. A Line could be used more than once but only one Line can be used per question. (0.25 points each)

  1. _____ Accumulate the sum of consecutive integers?
  2. _____ Assigns the initial value to variable sum?
  3. _____ Determines the starting integer to be summed?
  4. _____ Increments the value of variable num to the next consecutive integer?
  5. _____ Tests the condition that terminates the loop?
  6. _____ Causes the condition to become false when the loop is processed one more time?
  7. _____ Causes the condition to be true the first time through the loop?
  8. _____ Marks the top of the loop?
  9. _____ Marks the bottom of the loop?
  10. _____ Displays the result of the variable sum?

Part 2: Simple Programming—Quick Check/Desk Check

The order of the statements in a program can change the output of a program. Determine the value of the variable sum to be OUTPUT for each set of statements below by using the quick check approach. (2 points each)

11. [Insert code snippets or problem descriptions here for each case to determine output]

12. [Insert second code snippet or problem description here for the next quick check]

Part 3: Pseudo Code

13. Write an IF statement that assigns the text “False” to the variable answer when variable x=0; otherwise assign answer to “True”. Write an equivalent statement that has the same outcome but uses the opposite condition x 0. (2 points)

14. Fill in the blanks in the program below to produce the following output: -8, -4, 0, 4, 8, 12, 16

LET n = ______


DO WHILE n 

OUTPUT _____________


LET ____ = ______ + ______


LOOP

The Value of sum is

LET num = 1


LET sum = 0


DO WHILE num 

LET sum = sum + num


LET num = num + 1


LOOP


OUTPUT sum

The Value of sum is

LET num = 1


LET sum = 0


DO WHILE num 

LET num = num + 1


LET sum = sum + num


LOOP


OUTPUT sum

Equivalent IF statement

Original IF statement
