I wants answers of these questions according to the above code

Questions

1. In my take home assessment, I probably represented the date as its own structure. What is the advantage of making the date its own structure? Was I able to simplify my coding because it was represented as its own structure? If so, describe one example of where it allowed me to simplify or modularize my code. If having the date as its own structure did not simplify my code, can I think of how it might allow me to simplify or modularize my code?
2. To display the total sales for each date, I needed to compile this data. Describe how I did this. Was it done with separate data structures or an existing data structure? Did I compute it in an existing function or did I use a special function for the purpose? When did I compile the data?
3. When I sorted the sales data by revenue, which sorting algorithm did I use? Why did I select this algorithm?
