CMPUT 101 Lab # 2

September 17, 2007

14:00 – 16:50


Recap lab 1 guido

Recap Lab # 1: Guido

  • World (.wld)

    • Robot [ave] [street] [direction] [# of beeper]

      • Robot 3 2 E 1

    • Wall [ave] [street] [direction] [length]

      • Wall 3 4 S 2

    • Beepers [ave] [street] [# of beeper]

      • Beepers 1 4 6


Recap lab 1 guido1

Recap Lab # 1: Guido

  • Program (.gvr)

    • move, turnleft, pickbeeper, putbeeper, turnoff

    • All “define” instructions have to be at the beginning of the file.


Conditionals

Conditionals

  • conditional branching

    if <test>:   <block>

    if front_is_clear:    move

  • <block> indicates a set of instructions within the same indent.

  • All conditions you can use are listed in Step08 guide


Iteration

Iteration

  • while loop

    while <test>:

    <block>

    while front_is_clear:

    move

  • While do until the test condition is false.


Iteration1

Iteration

  • Do

    do <number>:

    <block>

    do 5:

    move

move

move

move

move

move


Part a

Part a

  • Step09:

    • use do, and if instructions

    • Guido will shut down if asked to pick up a beeper and there is not one there, which conditional to use?

    • check if wall reached. Which conditional will be used to check if wall reached?

  • Read Step08 first


Step08

Step08

robot 1 2 E

Beepers 3 2 1

Beepers 4 2 1

Beepers 6 2 1

Beepers 8 2 1

Beepers 9 2 1

Beepers 10 2 1

Beepers 12 2 1

Wall 12 2 E


Part b

Part b

  • use while instead of do,

  • street can be any length,

  • wall at the end


Part c

Part c

  • check for multiple beepers,

  • do we know how many? which conditional? while more beepers, keep picking up


Part d

Part d

  • traverse each row, pick up beepers, until North East corner reached.

  • Drop beepers, how would you check if any are in the bag?

  • See figures for example


Part e

Part e

  • Consider the map --- see figure

  • Use the program in part d but run in the new world

  • No need to write a new program

  • Answer the questions verbally


Keep in mind

Keep in mind

  • use block structures (routines) to simplify the code e.g. turnNorth, turnEast, sweepOneRow, etc.

  • students can work in teams of two, or three (if there is an odd number of students), or can also work individually

  • test with both sample worlds provided
