Homework Part 1

Problem 1: This problem involves parameters

Qais is writing code to calculate formulas from his math class. He’s currently working on a procedure to calculate average speed, based on this formula:

Average speed=

Total Time/Total Distance ​

• Highlight which of these is the best procedure for calculating and displaying average speed.
  • PROCEDURE calcAvgSpeed (distance, time) { DISPLAY (distance/time) }
  • PROCEDURE calcAvgSpeed (distance) { DISPLAY (distance/time) }
  • PROCEDURE calcAvgSpeed (distance, time) { DISPLAY (time/distance) = Answer }

Problem 2: Procedures with return values

James Hunter is looking through his classmate’s program and sees a procedure called heightenEmotions: PROCEDURE heightenEmotions(myEmotion)

{ moreEnergy ← CONCAT(myEmotion, “!!!”)

moreVolume ← UPPER(moreEnergy)

RETURN moreVolume }

That procedure manipulates strings using two built-in procedures, CONCAT for concatenating two strings together, and UPPER for converting a string to uppercase.

James Hunter then sees this line of code:

heightenEmotions(“im mad”)

After that line of code runs, will nothing be displayed?

True

False = Answer

• The procedure heightenEmotions takes a string as input, manipulates it using the CONCAT and UPPER procedures, and then returns the resulting string.

Problem 3: Procedures with return values

Bubz is writing a program to calculate the carbon footprint of his activities. The procedure calcFlightFootprint calculates the pounds of carbon dioxide produced per passenger in a flight that covers a given number of miles and seats a given number of passengers.

PROCEDURE calcFlightFootprint(numMiles, numPassengers) { CO2_PER_MILE ← 53.29

carbonPerFlight ← numMiles * CO2_PER_MILE

carbonPerPassenger ← carbonPerFlight / numPassengers

RETURN carbonPerPassenger

}

Bubz wants to use that procedure to calculate the total footprint for his two upcoming flights: LA to NY: 2,451 miles and 118 passengers NY to London: 3,442 miles and 252 passengers

Which of these code snippets successfully calculates and stores her total footprint? Highlight 2 answers.

1. totalFootprint ← calcFlightFootprint(2451, 118) + calcFlightFootprint(3442, 252) = Answer

2. totalFootprint ← calcFlightFootprint(2451, 118 + 3442, 252)

totalFootprint ← calcFlightFootprint((2451, 118) + (3442, 252)) = Answer

4. laNyCarbon ← calcFlightFootprint(2451, 118) nyLondonCarbon ← calcFlightFootprint(3442, 252) totalFootprint ← laNyCarbon + nyLondonCarbon

Part 2

PROCEDURE find a ()

{ c – 9

b <-- 9 * 9    

a <-- b * c     

Print (a)

}

What is a?
= 729 = Answer cost ⟵ 173 tax - 10%

PROCEDURE applytax (cost, cpercentDiscounted) { temp <– 100 + percentTaxed

temp <-- temp / 100

cost <-- cost x temp       

Print(cost)} 

What is the cost? = cost is $190.30 Tempature - 103 Degrees

PROCEDURE convet Fahrenheit (tempature)

{

Celsius <-- tempature - 32  

Celsius <-- Celsius x 5/9      

Print (Celsius)} answer = 39.444

# 3.13 part 1 and 2

### #1. Create a procedure that is meant to replace the top running backs yards per game in one season if the current running back has more yards per game

• Necessary Parameters: toprbyardspg(100), currentrbyards(1260), totalGames(12)

PROCEDURE updateTopRunningBack(currentRB, currentRBYardsPerGame, topRB, topRBYardsPerGame)

{ IF (currentRBYardsPerGame > topRBYardsPerGame) { topRB <– currentRB topRBYardsPerGame <– currentRBYardsPerGame } }

#2. Write a procedure that will allow the A+ to get to the 1, while avoiding the black boxes.

PROCEDURE getAplus(){ If (can_MoveForward): Move_Forward Else (can_MoveRight): Rotate_Right Move_Forward If (can_MoveLeft); Rotate_Left Move_forward }

#3. Which Is the Correct Way to define the Name of a Procedure?**

• A. PROCEDURE MYLIST
• B. PROCEDURE MyList = Answer
• C. procedure mylist

#4. Write A Procedure That gets the BeachBall To the Green Square

PROCEDURE BallToGreen{ Rotate_Left Move_Forward Rotate_Right Move_Forward( until count = 6) break Rotate_Left Move_Forward (until count=2) break }
