I am trying to draw a grid of squares. What should go in the empty line?

for (var i = 0; i < 400; i += 40) {

for (var j = 0; j < 400; j += 40) {

}}

• rect(i, j, 20, 20);

• rect(j, i, 20, 20);

• rect(i * 40, j * 40, 10, 10);

• rect(j, i, 40, 40);

Select everything you need to make a recursive function:

• recursive call (call itself inside the function)

• end condition (when does it stop calling)

• start condition (when does it start calling)

• passed parameters

True or False: The number of lines of code a project has is directly connected to how good the code is

What is the length of the array nums?

var nums = [];

for (var i = 0; i < 10; i++) {

nums[i] = [];

for (var j = 0; j < 10; j++) {

nums[i].push(random(100));

}}

What's wrong with this function?

var r = function(num) {

ellipse(200, 200, num, num);

r(num - 10);

};

• It will never end

• The ellipse won't appear because there is no fill

• Function names have to be more than one letter long

• Nothing - it will run fine

What is an appropriate case for this switch?

switch(mouseX > 200) {

• case true:

Which of these is NOT a real function?

• mouseOver();

• lerpColor();

• pow();

• breakLoop();

What text will appear on the screen?

var words = ["Gonna", "take", "my", "horse", "to", "the", "Old", "Town", "Road"];

text(words[28 % words.length], 200, 200);
