==Some Explanations==
 +
 
 +
* There are 2 new elements in the program:
 +
** <tt>float diameter</tt>, and
 +
** <tt>random( )</tt>.
 +
* <tt>float diameter</tt> simply says that '''diameter''' is used in the program as a ''variable'' that will contain a real number (real numbers are numbers with a decimal point).
 +
* <tt>random()</tt> is a function that returns a random number.  If you call <tt>random(10)</tt>, it will return a random number between 0 and 10, not inclusive.  So, when we write:
 +
 
 +
  diameter = random( 200 );
 +
 
 +
:we make the sketch store a random number into the variable diameter, and we force this random number to be larger than or equal to 0, and less than 200.
 +
:When we call '''ellipse()''' and write <tt>random(500)</tt> for both the ''x'' and ''y'' coordinates, we make the sketch put a circle in the window at a random position, but we force the center of the circle to remain inside the window.
 +
 
 +
==Your Assignment==
 +
 
 +
# make your sketch display circles only on the sketch only when the mouse button is ''pressed''.
