How do
x
and
y
change when moving an object down - left on the screen
both x & y decrease
both x & y increase
x decreases, y increases
x increases, y decreases
4
Will the result of the program below change, if
background(0);

it will show the text with size 50 pixels
it will fade the text gradually with speed 50 ms
no difference, both will draw a black background
it will erase the previous letters drawn on the screen
5
In Processing :
setup() and draw() are executed continuously
setup() and draw() are executed only once
draw() is executed continuously,but setup()is not necessary
draw() is executedcontinuously and setup() - only once
