All Classes
Please join my Google classroom for the appropriate period.
Class codes for Google Classroom will be coming soon:
CS 3 and Independent Study
I will need to take just 1 grade each week starting
next week. Due by Friday evening, you will need to
type up a summary of what you have done for the week.
It does NOT have to be elaborate.
You will need 100+ lines of code.
This is lines of code, NOT blank lines and comments.
(or an appropriate amount of code on codecademy.com)
Example 1:
I have worked on C++ on codecademy.com this week.
I have done lessons 1-4.
Here is a screenshot of my progress (show entire screen with profile icon).
Example 2:
I have worked on my chess game.
I added checks for the pawn movement,
and the King and Queen movement.
Here is the code that I wrote this week.
(ASCII code attached)
