What is wrong with the following pseudocode?

Declare Count As Integer

Declare TheNumber As Integer

Set TheNumber = 12

None of these are correct ouput1, 2, 2, 44, 5, 5, 63, 4, 6, 8

Question 10

What does the following program segment do?

Declare Count As Integer

Declare Sum As Integer

Set Sum = 0

Set X = 10/N

Write X

Set X = Int(X)

Write X

End For

Enter only the numbers in the space provided.)

Declare Coin As Integer

Declare X As Integer

For (X = ; X <= ; X++)

Set Coin = Floor(Random() * 2) + 1

Select Case Of Coin

Case 1:

Write “Heads”

Break

Case 2:

Write “Tails”

Break

Default: Break

End Case

End For

Enter only the numbers in the space provided.)

Declare Die, X As Integer

For (X = 1; X <= 10; X++)

Set Die = Floor(Random()* )+

Question 171 pts

What is the first output corresponding to the following pseudocode? (Note, this question has 2 parts; you must answer each part correctly to receive full marks. Enter only the numbers in the space provided.)

The first iteration displays the value and

Declare M As Integer

Declare P As Integer

Repeat

Set P = 1

While P < 4

Explanation / Answer

Q1: What is the output of the code corresponding to the following pseudocode? (In the answer options, new lines are separated by commas.)

Declare X As Integer

Declare Y As Integer

For (X = 1; X <=2; X++)

For (Y = 3; Y <= 4; Y++)

Write X * Y

--------------------------------------------------------------------------------------------------------------------------------------------

The loop of X will be executed two times X=1 and X=2. for each value of X, the loop of Y will be executed for Y=3 and Y=4

SO we get 3,4,6,8 as output

-----------------------------------------------------------------------------------------------------------------------------------------------------

Question 2 Which of the following loops cannot be nested in a For loop?

Repeat ... Until

Do ... While
For
All of these can be nested in a For loop

Ans: All of these can be nested in a For loop

--------------------------------------------------------------------------------------------------------------------------------------------------------

Question 3

What is the output of the code corresponding to the pseudocode shown?

Declare G As Integer

Declare H As Integer

Set G = 7

While G <= 8

Set H = 6

While H <= 7

Write G + H

Set H = H + 1

End While(H)

Set G = G + 1

End While(G)

7, 6, 7, 813, 14, 14, 157, 6, 7, 7, 8, 6, 8, 713, 14, 15

-------------------------------------------------------------------------------------------------------------------------------------------------------

Output

so we get 13,14,14,15 as Output

-----------------------------------------------------------------------------------------------------------------------------------------------------

Question 4

What will be displayed after code corresponding to the following pseudocode is run?

Declare A As Integer

Declare B As Integer

Declare C As Integer

Set A = 3

While A <= 6

Set B = (2 * A) – 1

Write B

Set C = A

While C <= (A+1)

Write C

Set C = C + 1

End While(C)

Set A = A + 2

End While(A)

5, 3, 3, 9, 5, 55, 3, 4, 9, 5, 65, 3, 9, 53, 5, 4, 5, 9, 5

------------------------------------------------------------------------------------------------------------------------------------------------

Output

So output will be 5,3,4,9,5,6

X Y X*Y 1 3 3 1 4 4 2 3 6 2 4 8
