Create a form in which the user enters two separate numbers (x and y), and when the user clicks the appropriate button, math functions are performed on these two numbers and output back on to the form.

INPUT

User can enter two separate numbers (one for the x variable, and one for the y variable)
User can input their information:
- The user must be able to enter information about themselves, including first name, last name, address, phone

PROCESSING

The user will be allowed to click a button (or multiple buttons if desired) on the form
Store the user input into two separate variables to be able to perform math
Once the button(s) is clicked, several math functions must be performed
- Adding x and y
- Subtracting x and y
- Multiplying x and y
- Dividing x and y

OUTPUT

After the button is clicked and the math functions are performed, the answers to the math problems should be output on the form
- Addition =
- Subtraction =
- Multiplication =
- Division =
Output the data into a listbox
Output the data into text box

CRITERIA

Make the form visually appealing – use alignment, formatting, spelling, font controls, etc.
Must be usable (tab order, adequate labels)
- Include a clear button so the user can start again
Make use of methods we have learned in class
Variable names can be creative, but they must include the appropriate prefixes
Include access keys on each button
Set tab order from top to bottom
Include field masking where appropriate
Use at least one input box
Display at least one output box
Include documentation within code
Must give accurate information when performing functions
Any other special instructions mentioned in Input, Output or Processing section

GRADING

Creativity
User friendliness of form
Use of multiple methods discussed in class
Include all criteria listed above

SUBMISSION INSTRUCTIONS

Must be submitted to BlackBoard drop box No LATER THAN midnight on the due date

All files should be included in submission

Using an ArrayList, create a program which does the following: If the user enters quit, the program ends. If the user enters add followed by a string, program adds the string only to your ArrayList. If the user enters print, the program prints out the ArrayList contents. If the user enters size, the program prints out size of ArrayList, If the user enters remove followed by string, it removes all strings. interface example: **** Welcome to my List Program ****...

Write a C++ program that reads numbers from the user until the user enters a Sentinel. Use a Sentinel of -999. Ignore all negative numbers from the user input. Do the following: Output the sum of all even numbers Output the sum of all odd numbers Output the count of all even numbers Output the count of all odd numbers You must use loops and numbers to do this. You must not use any arrays or vectors for this program.

Write Java code that allows a user to repeatedly enter numbers. Each time the user enters a number, the program should print out the average of the last 3 numbers (or all numbers if 3 or less have been entered). I would like a detailed explanation so that a beginner level Java programmer could understand.
