Concetti Chiave
- The code defines a "Prodotti" structure to store product details including a product code, description, price, and quantity.
- A maximum limit for product entries is set to 100 within the defined array size using the constant MAX.
- Functions are implemented to request dimension, load products, sort them, and display the list, ensuring structured handling of product data.
- The sorting function arranges products based on their product code, using a swap function to interchange values of the structure's elements.
- Console input and output are used to interact with the user for data entry and to display the sorted product information.

Domande da interrogazione
- What is the purpose of the `Prodotti` structure in the code?
- How does the program ensure that the number of products does not exceed a certain limit?
- What is the role of the `Ordinamento` function in the program?
The `Prodotti` structure is designed to store information about products, including their product code, description, price, and quantity. This structure is used to manage and organize product data within the program.
The program uses the `ChiediDimensione` function to prompt the user for the number of products. It includes a validation loop that ensures the entered number does not exceed the defined maximum limit (`MAX`), which is set to 100.
The `Ordinamento` function sorts the array of products (`articoli`) based on their product codes in ascending order. It uses a nested loop to compare and swap elements using the `Scambia` function to ensure the products are ordered correctly.
