Remember the “Sierpinski Carpet” from last week!
Part 1
Write a C++ program to generate (x, y) points according to the following rules:
(xnew, ynew) r
(0.5, 0.27*y) for r<0.02
(-0.139*x+0.263*y+0.57, 0.246*x+0.224*y-0.036) for 0.02<=r<=0.017
(0.17*x-0.215*y+0.408, 0.222*x+0.176*y+0.0893) for 0.17<r<=0.3
(0.781*x+0.034*y+0.1075, -0.032*x+0.739*y+0.27) for 0.3<r<1
where r is a uniform random number in the interval [0,1). Use as starting values for your
program (x,y) = (0.5, 0.0). Run the program, and plot your results. After plotting choose an
appropriate name for your plot. Remember, when developing your program adhere to our
programing standards. You can use your source code from part 1 as a starting point.
Part 2
Post this exercise to your computational physics website. Create a html page for Project 3.
Create a link from your main project web page to this html page. This html page should include the
following heading information: exercise (project) title, exercise number, your name, & today’s date.
The main content of this page should include the following:
–a short description of the execise in Part 1
–a link to the source code file
–the text region which contains the actual source code text
–the plot image
