Question

Programming question. Using Visual Studio 2019 C#

Windows Form Application (.NET Framework)

Please include code for program with ALL conditions met.

Conditions to be met:

Word Problem A person inherits a large amount of money. The person wants to invest it. He also has to withdraw it annually. How many years will it take him/her to spend all of the investment that earns at a 7% annual interest rate? Note that he/she needs to withdraw $40,000.00 a year. Also there is an inflation rate that must be considered in a calculation. Create a C# project that allows the user to enter an inherited amount. If it is not entered, the program will display an error message. There must be two options on the form for the user to select an inflation rate percentage: Option 1: 3% inflation rate Option 2: 4% inflation rate Here are additional conditions: 1. If the inherited amount is less than or equal to $40,000.0, the message"You will need it this year. No investment needed." Otherwise, a calculation will be performed. 2. When the form is loaded, a relevant picture is loaded to the top left of the form with a welcome message "Welcome to Inheritance calculator". Any picture would be fine actually. 3. After the user selects an inflation rate and enter an inherited amount and a calculate button is clicked, then a list of details in the following format will be displayed: inflation rate. Your investment starts at $ and earn 7% a year. You withdraw $40,000 a year. You have chosen a Year Interest earned Balance 2015 2014 0 (This could be a negative value too.) It takes you years to spend all of your inheritance. Controls required are as follows: -Buttons, (Radio Buttons or Check Boxes; you must make a good decision which to use), List Box, Textboxes, labels, PictureBoxes, and GroupBoxes. - The program runs without errors. -The program generates a desired output. - The program validates user's input. -The program contains named constants. -The program uses at least one loop. -The program uses conditions. -The program uses appropriate variables and data types. -The program is easy to read (indentation) -The program contains a form with controls required.
