Final Calculator implementation ready for review

[Brandonscodedata]

Create a functionality that will count the amount of times the calculator was used.

Store a list with the latest calculations. And give the users the ability to delete that list.

Allow the users to use the results in the list above to perform new calculations.

Add extra calculations: Square Root, Taking the Power, 10x, Trigonometry functions.

@Brandonscodedata Sorry about the delay. Project approved! 😄✅ I'm glad you did a bunch of the challenges, that's what takes your learning to the next level!😊

👩‍🏫Feedback

🔍️There’s also a small logic issue around reusing history. The following structure:

if (historyInput == "d")
{
    ...
}

if (historyInput == "u")
{
    ...
}
else
{
    usePreviousResult = false;
}

means choosing "d" subsequently reaches the else belonging to the second if. An else if structure would make the menu flow clearer and less error-prone.

🕵️‍♀️Also, have a look at our style guide since there are a few issues in your code. e.g. lots of unused usings and unecessary comments, as per picture below. You can read our code conventions here🤓.

🧐Challenges Review

✅ Calculation history is implemented with the CalcData model and a List.
✅The user can clear their calculation history.
✅A previous calculation result can be selected and reused in the next calculation.
✅Additional operations were added, including square root, nth root, powers of 10, sine, cosine, tangent, and logarithms.

🗺️ Suggested next step

I noticed that you already complete a few courses. I'd highly recommend taking our LINQ Fundamentals course next. LINQ is one of the most important tools in modern C# and becoming comfortable with it will make your code much cleaner and more expressive.
