CMU 15-112 Fall 2015 Quiz7 Practice
(Due never)

• Edit how you wish (add imports, helper functions, etc), except:
  • Do not use recursion, lambdas, or non-local variables this week.
  • Do not edit the test code.
  • Do not hardcode the test cases in your solutions.
• Quiz6 will include a subset of the problems here.

1. Code Tracing
2. events-example3
3. drawLinePattern(canvas, x0, y0, x1, y1)
4. drawGrid(canvas, left, top, right, bottom)
5. Connect4

1. Code Tracing
   See here.


2. events-example3
   Be sure you thoroughly understand and can easily derive everything except the run() function in events-example3.py.


3. drawLinePattern(canvas, x0, y0, x1, y1)
   Write drawLinePattern from here (see question 2.3), which draws this:
   


4. drawGrid(canvas, left, top, right, bottom)
   Write drawGrid from here, which draws this:
   


5. Connect4
   Write a graphical version of Connect4, which works like the one we wrote this week in recitation. You should support both mouse-based and key-based moves. Furthermore, you should include a timer such that each player only has up to 3 seconds to play their turn. If a player runs out of those 3 seconds, the turn swaps immediately to the other player. As we did before, you should use wordSearch to do the actual checking for a win. While you are required to be able to write wordSearch from scratch, we are reall focusing on the graphics and animation portion in quiz7.
