130 recap and homework for Tuesday, January 24

We got through page 11 of my Logo work. See corrected page 11 here if you missed class.

Assignment for next week:

• Polygon — well, we did that in class, so rather than submit it, make sure you understand it! Think about variations: Add a third variable for orientation, to draw left or right. Create a procedure for a parallelogram with side lengths and one angle specified. Rather than a polygon with n sides, how about a star with n sides?
  


• Multisquare — a lot of squares together. More challenging: a Multipolygon, with polygons nested so that they are not touching. Use repeat and a variable to make this routine as short as you can!
  
  Here are examples of multisquare and multipoly.
  
  
  
  
  
  


• Howmany procedure — like howlong on page 11, except that rather than give the length of the word, it tells how many of a given letter occur in the word. This is a challenging problem!
  

Please submit each program in a separate e-mail to vfitton@nvcc.edu. You may attach a program file (with suffix .LGO) if you like — see about files later in my book — or just cut and paste the text of your procedure into an e-mail.

For submissions, please use subject lines "130 multisquare" and "130 howmany"; for questions, please use the subject line "130 question" — and don't forget to include the code that shows your problem!
