Question

What does this program do?

function drawCircle(x, y, radius, color){
var circle = new Circle(radius);
circle.setPosition(x, y);
circle.setColor(color);
add(circle);
}
function start(){
setTimer(draw, 50);
}
function draw(){
var color = Randomizer.nextColor();
var centerX = getWidth()/2;
var centerY = getHeight()/2;
var radius = 100;
drawCircle(centerX, centerY, radius, color);
}
a) Draws a square on the canvas.
b) Creates a bouncing ball animation.
c) Draws a circle in the center of the canvas.
d) Generates a random pattern on the canvas.

Answer 1

The program draws a circle in the center of the canvas and changes its color at regular intervals to create a visually dynamic effect.

Step-by-step explanation:

The program provided in the question uses a graphical function to draw a circle on a canvas in a web browser or similar environment. The drawCircle function is designed to create a circle object with a given radius, position, and color. The start function sets a timer to repeatedly call the draw function every 50 milliseconds. In the draw function, a random color is generated for each circle, then it places the circle with a fixed radius of 100 pixels in the center of the canvas. Since the timer repeatedly calls the draw function, it results in a circle that changes color rapidly, creating a visually dynamic effect on the canvas.
