When completing your code challenges keep in mind the four characteristics of quality code…

1. Functional – Accomplishes it’s task every time.
2. Readable – Easy for a human to read and edit
3. Efficient – Executes quickly without unnecessary steps.
4. Short – Uses the fewest lines of code.

Or put another way…

1. Does it work? Your code should meet all of the requirements and work in every situation.
2.  Is it understandable? Your code should be easy for a human to read and understand.
3. Is it fast? You code should execute and finish as quickly as possible.
4. Is it short? Your code should be as few line of code as possible.

Submit Your Programming Challenges here. Please make sure your challenge meets all of the requirements before submitting. Also please make sure your app is titled “Programming Challenge #__” to make it extra clear which challenge you have completed.

1. Four Function Calculator App – Create a basic four function calculator. Remix this template to start. Watch a video example to see how it should work here.

13. Draw A Polygon – Write a function drawRegularPolygon(numberOfSides, sideLength) that draws a regular polygon with a given number of sides and a given side length.
    • The polygon should be drawn in front of, and to the right of, the turtle.
    • The turtle should end in the position and orientation it started at before the function was called.
    • The bottom line segment of the polygon should be perpendicular to the starting position of the turtle.
    • The numberOfSides variable will never be less than three since there is no polygon with less than three sides.
    • View an example of a custom function with parameters.

The turtle should end at the position and orientation where it started. View Example Code.
    • You may use functions, loops, parameters, and the commands moveForward(), turnLeft(), and turnRight();
    • Some example code that we talked about in class that illustrates using parameters in your function. You might also consider looking at your Turtle Challenge#13 as an example.

Below are several recommended calculators…

• TI-30XS MultiView Scientific Calculator ($19, $15) – This is one of my favorite calculators and is highly recommended. Definitely the best value for the your money and will help you a lot.
• TI-84 Graphing Calculator ($96, $110) – There are lots of models of the TI-84 and they are all very similar. This is the most popular This model of calculator that we have in the classroom. This calculator is expensive but is the standard calculator that is used all throughout college.

Below are several recommended calculator apps. Apps work well on homework but cannot be used on tests…

• Desmos for iPhone or Android. This app is also available on the computer at desmos.com and is the future
• Scientific Calculator for iPhone or Android (AdFree). These are the two best basic calculator apps for your phone.
• TI-84 for Android. This app is a clone of the physical TI-84 Plus calculator listed above
• Symbolab online. This is an algebra tool that can solve many basic algebra problems.
• Math Papa for iPhone or Android – Another algebra tool that can solve many basic algebra problems.
• Other useful websites and apps include Wolfram Alpha, PhotoMath, and Tiger Algebra
