==================================================

Question: Why do we use functions in programming?

Answer: Break down our program into smaller parts

Avoid repeating code

Make our program more readable

==================================================

Question: What is a top down design?

Answer: Top down design is a way of designing your program by starting with the biggest problem and breaking it down into smaller and smaller pieces that are easier to solve.

==================================================

Question: What is a code comment

Answer: A way to give notes to the reader to explain what your code is doing

Easier for other people to understand

Indenting is a key part of good programming style

Question: Which answer choice describes the game with the lowest level of abstraction?

Answer: First, Steph Curry flexed his left and right quad muscles at the exact same time, then he flexed each muscle in his fingers…

==================================================

Question: Karel needs to pick up a pile of tennis balls.

Which of the following start functions solves the problem at the highest level of abstraction?

Answer: function start() {

moveToPile();

takePile();

}

==================================================

Question: 2.8.4: Abstracting Your Day

Answer: I made this: Its dumb don’t blame me. (Basic 101)

  • I slipped on my shoes.

  • - I first had to put on socks. Then I used my right hand to pull the tag of the shoe so it can slip on.

  • - I first clapped down on the sock with both hands and gradually made it slide up my foot. Then I increased tension in my right hand so I can pull the tag of the shoe, when I got hold of the shoe. I relaxed my fingers except my pointer finger. And I pulled on the tag gently so the shoe can slip on.

  • I played COD (Call of Duty)

  • - I first took out the xbox controller and then I booted the xbox. After that I started to play COD.

  • - I first took the xbox controller off the counter with minimal effort of my muscles. Then I booted the xbox with my pointer finger. After that I sat down resting my glutes. Then I relaxed my fingers on the stick layout. And I started to play, after a while my fingers and my muscles started to get tense from all the action.

  • ==================================================

  • Question: 2.8.5: Reflection: Abstraction

  • Answer: What is abstraction? Describe it in your OWN words.

  • For instance if I use less abstraction it is going to be easier to understand. Less abstract. Like the art. But if I use high abstraction then it is going to be harder to understand. Like it is just said, not explained.

  • Example:

  • Less -> Well I played GTA 6 today. I know it is not released yet, but I got to have a chance to play it on the Asus PC that has RTX 2080 ti graphics that are in sli. Meaning I got buttery smooth games, and lets not start talking about the 4k resolution. Well I first was pumped to play a unreleased game. Second, I got handed the controller from my admin who was at the convention hosting the GTA 6 gameplay feed. Then I started to “grind” and play some missions. Soon my fingers went from relaxed to “gaming mode” and I felt as if I was in the game.

~ This did not happen. :D

==================================================

Question: 2.8.6: Abstraction in Karel

Answer: Abstraction helps us write programs by:

When we want to create something such as a function/command we need to explain it in detail. Meaning we need to add less abstraction to help us understand the command in a simpler way.

Less Abstraction: Less abstracted - Abstract art. Less abstract more details.

More Abstraction: More abstracted - Abstract art. More abstract less details.

Question: 2.20.4: Pseudocode

Answer: //Don’t copy this MAKE your own

MileStone 1:

First to build a tower:

Turn left

Then place a for loop:

putBall();

move();

putBall();

move();

putBall();

}

MileStone 2:

To come down:

Turn right //Because I am using “basic” Karel I have to make a function for that.

repeat 3 times

move

Turn left

}

MileStone 3:

Make function for make tower

//which is what the loop will be

putBall();

move();

putBall();

move();

putBall();

}

MileStone 4:

Make another function for basic Karel to turn Right

turnLeft();

turnLeft();

turnLeft();

}

MileStone 5:

Debug and run

Question: 2.20.2: Brainstorm and Discuss

Answer: //Easy

Function Creator (Make Karel do a Backflip) (Then go around the perimeter.)

What is the project idea? What will you create?

This will show that you the difference from Ultra and Basic Karel.

What is the purpose of this project idea? Why do you want to make this?

The purpose should create a challenge that isn’t hard or easy. This pushes you create anything that still orders the Backflip and perimeter run.

What are some specific functions you’ll need to write to create this project?

function (If front is Blocked) Function (If Clear)

How long do you think this project will take to complete?

At least 45 minutes

==================================================

Question: 2.20.6: Reflection

Answer: //This is mine that connects with MY code. Use as reference.

For my program, I had used language of JavaScript to create it. The purpose of my program is to make a Karel make towers, while placing balls on each row/column. The game is also supposed to help you grow out of your zone and create more to it. (Open Source). When the creation of the Tower you can make Karel paint, turn around, do a backflip, etc. Abstraction helps, because it is easier to read the broken down code. Also, with the repeat/for loop function this cuts the code to be smaller and easier to understand. With debugging it took me at least 45 minutes. But next time I would add some cool/custom unique characteristics such as a rainbow border. This is possible with basic, Super, and Ultra Karel. Just takes some time to create something fundamental. Goal achieving project.
