THis is the first assignment we got this year. Can u help me out?

Now write a program that divides the screen canvas into four rectangles on the screen. The point where the four rectangles coincide should follow the mouse, therefore resizing the rectangles as the mouse is moved. When the user clicks any mouse button, each rectangle should change to a different random colour. You will need to investigate the use of the random() function to achieve this.

void setup() {
size(500, 500);
}

void draw() {
background(200);
rect(0, 0, mouseX, mouseY);
rect(mouseX, mouseY, 500, 500);

}

This is the best I can do now.........

So lucky! Made 1 pretty quick!

// http://forum.processing.org/topic/processing-question

final static byte SQUARES = 4;
final static color[] colors = new color[SQUARES];

// Choose JAVA2D, P2D, P3D or OPENGL:
final static String ENGINE = P2D;

void setup() {
  size(01510, 01510, ENGINE);
  noLoop();
  noStroke();
  noCursor();
  rectMode(CORNERS);  // CORNER works too!

  mousePressed();
}

void draw() {
  fill(colors[0]);
  rect(0, 0, mouseX, mouseY);

  fill(colors[1]);
  rect(mouseX, 0, width, mouseY);

  fill(colors[2]);
  rect(0, mouseY, mouseX, height);

  fill(colors[3]);
  rect(mouseX, mouseY, width, height);
}

void mousePressed() {
  redraw();

  for (byte c = SQUARES; c != 0; 
  colors[--c] = (color) random(0x1000000) | #000000);
}

void mouseMoved() {
  redraw();
}

void mouseDragged() {
  redraw();
}
