Microsoft 98-380 Valid Test : Introduction to Programming Using Block-Based Languages (Touch Develop)

You are creating a calculator app. The Power function must calculate the result of raising a number by a positive exponent value.
You create the following pseudocode:
Function Power(number, exponent)
DECLARE result
End Function
You need to complete the pseudocode for the function.
Which pseudocode should you use?

• A. WHILE exponent > 1 SET result TO result * number SET exponent TO exponent +
  1LOOPReturn result
• B. IF exponent > 1 SET result TO result * number SET exponent TO exponent + 1END
  IFReturn result
• C. IF exponent > 1 SET result TO result * number SET exponent TO exponent - 1END
  IFReturn result
• D. WHILE exponent > 1 SET result TO result * number SET exponent TO exponent -
  1LOOPReturn result

DRAG DROP
You are creating a graphic that illustrates an overview of the entire software development life cycle.
Which order correctly describes the steps that occur prior to release and deployment? To answer, drag the appropriate step to the correct position in the life cycle. Each action may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

HOTSPOT
Baldwin Museum of Science wants you to build a virtual tour guide app that visitors will use at the museum. The museum conducts a user survey which indicates that the app must meet the following requirements:
*
Users will scan a QR code to find more information about the exhibits.
*
Additional information is provided through an augmented reality (AR) view. The AR view will be displayed on top of the live direct view of the exhibit.
Due to time and budget constraints, the app can only support limited types of devices at this stage. You want to make sure that app provides the best possible user-experience based on the user survey.
You need to identify the appropriate types of devices the app should support.
For each type of device, select Yes if it is appropriate. Otherwise, select No.

HOTSPOT
You are creating an app for Alpine Ski House.
Players will move a skier between pairs of flags as the skier moves down the slope. The number of flag pairs that a user must successfully pass is three times the player's level.
Flag1 is displayed on the left and Flag2 is displayed on the right, as shown in the exhibit.
(Click the Exhibit tab.)
When the skier outside the flags, the skier will crash into an obstacle and the following actions will occur:
*
The player will lose one life.
*
An animation will play
*
A sound will play.
The player starts the game with 10 lives. If the player's life becomes 0 before the skier reaches the bottom, the skier crashes and the game ends. If the skier reaches the bottom the player gains one level.
You need to design the algorithm.
Which pseudocode should you use? To answer, select the appropriate pseudocode segments in the answer area.
NOTE: Each correct selection is worth one point.

HOTSPOT
You are helping some of your brother's friends with their math homework. Each of them writes down the problem and solves it. Two of your brother's friends have the same answer, while the third has a different answer.

You need to determine which friend used the correct logic to answer the problem.
For each of the following statements, select Yes if the statement is true. Otherwise, select
No.
NOTE: Each correct selection is worth one point.
