CompSci 94 Fall 22 Test 2 Solution

Problem 1 Part A

1) Pig says no, then pig says yes

2) Penguin says yes, then penguin says yes

Problem 1 Part B

1) pig says "red"

2) penguin says "blue"

3) creature penguin,  number anything < 2.0 and color is "blue"

For example creature = this.penguin, somenumber = 1.0 and color = "BLUE"

Problem 2

Part A
1) 20 times
2) 5 times

Part B
1) 3 times
2) I'm this far from you 1.5

Part C
1) 2 times
2) I'm this far from you 0.0

Problem 3

A) The animals turn to the right, all the way around once, one at a time in
the order they are in the animals array. bunny first, then hare, then
panda, then pig

B) The animals in the array (bunny, hare, panda and pig) all move right one
unit at the same time.

C) All the animals in the animals array (bunny, hare, panda and pig) all
say go at the same time, then duke at the same time, and then blue at
the same time

D) It is not possible to add a Cow to the Biped array because a Cow is a
quadruped. 

Problem 4

declare procedure resizeRandomly with parameter: Decimal Number somenum

do in order
randomNum = nextRandomWholeNumberInRange1,3
if randomNum == 1 is true then
    this resize somenum
else
   if randomNum == 2 is true then
        this resize 1.4
   else
        this resize 0.6
   

Problem 5

declare procedure colorful with parameter: Paint newColor, Biped animal

do in order

animal setPaint newColor
DecimalNumber originalHeight = animal getHeight
while animal getPaint not equal to BLUE is true
    animal resize Randomly somenum = 2.0
    if animal getHeight > originalHeight * 2 is true then
         animal setPaint BLUE



Problem 6

Bunny Procedure
declare procedure visit with parameters Biped creature

  do together
      this.turnToFace creature
      creature turnToFace this
  while bunny distanceTo creature > 2.0
      bunny walk
  if bunny.getHeight < creature.getHeight is true then
      this.resize 1.2
  else
      creature.resize 1.2


Problem 7

Bunny Procedure
declare procedure repeatedVisits with parameters Biped animal1, Biped animal2, WholeNumber loopcount

count up to loopcount
   if this.getDistanceTo animal1 > this.getDistanceTo animal2 is true then
          this visit animal1
   else
          this visit animal2
