New Concept: Complexity and organization
This example program uses simple concepts you’ve seen before, but it’s a much longer program! Don’t get overwhelmed by the number of lines of code; try to break down the concepts into pieces and understand each piece. Once you understand the pieces, it’s easier to ‘zoom out’ and look at the program as a whole.
Notice the use of comments and line breaks throughout this program. Remember that the computer doesn’t need line breaks, blank lines, or comments for the program to work - those are tools for humans. When you are tinkering with code, remember to leave yourself notes and comments so the code is overwhelming if you come back to it later.
