JAVA LANGUAGE

Instructions

1. Review the Notes - Arrays, Notes - Loops, etc., and the Code Conventions, Template, and previous comments and discussion posts.
2. Start with your program from the A4a - Calculator - Two Numbers submission. Make sure you have a backup copy before you get started.
3. Fix it based on the previous assignment comments, including A3 - Simple Calculator. If you have yet to receive feedback for A4a - Calculator - Two Numbers, please e-mail me immediately and politely ask me to review your A4a submission. Please keep in mind, the sooner you get started, the sooner I will be able to provide you with feedback, so you will be able to complete this assignment by the due date.
4. Change your previous Calculator program as follows:
   • The following items must be completed or you will automatically get a zero for this assignment!
   • Fix any issues as per the comments for A3 and A4a
   • Use only the concepts covered through Module 5; see the Module Overviews, videos, and notes; do NOT user-defined methods other than main(), etc.
   • Create at least one fixed array declared at the top of main() with a size of three to hold the numbers inputted by the user
   • Nest for loops into your code to process the array appropriately, for example:
     • If the user selects from the menu to add the numbers, the numbers in the array get added together, e.g., 1.5 + 2 + -3 = 0.5
     • Note: When it comes to things like subtraction or division, it will work like this: 1.5 - 2 - -3 = 2.5 or 1.5 / 2 / -3 = -0.25
     • Then, the numbers and the result will get displayed to the user based on the following format:

       Answer: 1.500 + 2.000 + -3.000 = 0.500

   • The above is not quite as simple as you might think, so make sure you really think about how the computer/program processes an array to achieve the correct results
   • Keep in mind, if there is an error, your program should stop processing the array, and then, just display the appropriate error message, for example:
     • If the user enters: 1 0 3, and selects division from the menu, the array should only be processed up to 0
     • At that point, the error message would be displayed
     • Then, the program would continue by displaying the menu again
     • Hint: Use a logical operator in the condition of the for loop, but be careful you use the correct logical operator and put the conditions in the correct order
   • Since you can use loops and arrays now, you shouldn't need any stacked if or if-else constructs
   • All other aspects should work as previously indicated in A4a - Calculator - Two Numbers, except using loops and arrays as appropriate; if you think you figured out a more efficient way to process a menu item, discuss it with me
5. Make sure your comments and code completely follow the Code Conventions, are well-organized and easily readable, follow good programming practices, etc.
6. Make sure your output is professionally written.
7. When thoroughly testing your program change the size of the array at the top of main() to a larger number of elements.
8. Copy and paste your comments and code into a Microsoft Word document. Do NOT change it inside the Word document except as follows: If you comments and code are not completely visible inside of Word, select all of your comments and code, and change the font color to black.
9. Save and close the Word document.
10. Attach and submit the Word document via this assignment.
11. Verify what you submitted is the correct document.
12. E-mail me if you would like feedback, so you can fix any issues before the due date. Keep in mind, you will need to give me a few days before the due date to complete this process.
