Application Requirements

Explore how to define application requirements for processing CSV sales data with C++17. Understand loading files, parsing data with date filters, and computing sums, preparing for serial and parallel implementations in this practical lesson.

We'll cover the following...

Imagine you’re working with some sales data and one task is to calculate a sum of orders for some products. Your shopping system is elementary, and instead of a database, you have CSV files with the order data. There’s one file per product.
