Question

Write a C program

The Visual Studio project itself must make its output to the Console (i.e. the Command Prompt using printf) and it must exhibit the following features as a minimum:

• 3%: Looping Menu with 3 main actions: View Cars, Sell Car, View Sales
  • Note: A Car is defined by its price and model
• 3%: Must contain at least three arrays to record sales figures (maximum of 10 Car models)
  • Two for recording the price and model of one vehicle
  • One for recording the remaining amount of each car model
• 3%: Viewing Cars will show a list of models and remaining amount
  • 3%: Sorted by remaining amount in descending order
• 5%: Selling a Car needs to record the price and update existing arrays to reflect the sale data
  • 5%: Any data being accepted from the keyboard needs to be validated and filtered (i.e. only accept correct data from the user and keep asking until correct data is entered)
• 5%: Sales figures are displayed as a total sum for each Car model
  • 5%: Sorted by total sale amount in descending order
• 5%: Sales data is to be stored in a file
  • 7%: When the software launches, it should read previous sales data from the file, if it exists, to be used as starting data
• 2%: Exiting the software thanks the user for using it before closing
• 10%: Make use of topics not taught in the module, but can be applied in a relevant way to this software project (do not include features/topics just for the sake of showing that you know how to use/implement it, instead consider why it will improve the software for the user)
• 4%: Your code needs to follow recommended coding standards and good practice
• 5%: Also submit a Logbook containing Pseudocode (1%), Activity Diagram (1%), and Testing (3%) appropriate for your project
• Total: 65%
