 10 // Quiz #1
 11 // III. Programming Exercise
 12 // Write a class named Circle with fields named radius, area, and
 13 // diameter. Include a constructor that sets the radius to 1. Also
 14 // include public methods named SetRadius(), GetDiam(), GetArea(),
 15 // ComputeDiameter() which computes a circle's diameter, and
 16 // ComputeArea() which computes a circle's area. (The diameter of a
 17 // circle is twice the radius. The area is Pi (3.14) times the square
 18 // of the radius.) Turn in your source code for this program.
