What is negate?

Write the code

100

 Write a code using the OR operator that will run a TRUE value. (You do not need to use function start)

What is 

var (name) = true/false

var (name) = true/false

one variable is true

200

Write a code using the AND operator that will run a TRUE value. (You do not need to use function start)

What is 

var (name) = true

var (name) = true

both variables must be true

300

This code will run:

var pokemonPikachu = true 

pokemonPikachu = !pokemonPikachu 

What is false

NotpokemonPikachu

400

This code will run:

var show = readBoolean("Do you want to see a movie?");

var games= readBoolean("Do you want to play games?");

var havePlans = show || movie;

println("Do you have any plans?" + havePlans)'

What is

z==8

(z % y) + 4

What is 6

Interpret the code

100

19 == 19 || 19!=8

What is true?

200

var SIDE_LENGTH = 100;

function start(){

    var rectX = getWidth() / 2 - SIDE_LENGTH / 2;

    var rectY = getHeight() / 2 - SIDE_LENGTH / 2;

    var square = new Rectangle(SIDE_LENGTH, SIDE_LENGTH);

    square.setPosition(rectX, rectY);

    square.setColor(Randomizer.nextColor());

    add(square);

}

What is Random color square?

300

var i = 10;

while(i >= 0){

     println(i);

}

What is infinite loop (program crash)?

while(i >= 0){

     println(i);

     i--;

}

What is countdown 10 to 0?

500

var NUM_CIRCLES = 30;

var BIG_RADIUS = 150;

function start() 

{

    // Calculate constant values:

    var xPos = getWidth()/2;

    var height = getHeight();

    var increment = BIG_RADIUS / NUM_CIRCLES;

    

    // Draw circles:

    for (var i = NUM_CIRCLES; i > 0; i--)

    {

        var circle = new Circle(i * increment);

        circle.setColor(Randomizer.nextColor());

        circle.setPosition(xPos, height - circle.getRadius());

        add(circle);

    }

}

What is circle in circle?
