This `ModificaCampi` function in C++ presents a menu for updating...

This ModificaCampi function in C++ presents a menu for updating fields of a Paziente (Italian for "Patient") structure or class. Here's a breakdown of what the code does:

1. Prints a menu: It displays a prompt to the user asking which field of the Paziente structure they would like to update, offering options for fields such as Nome (Name), Cognome (Surname), Data di Nascita (Date of Birth), Residenza (Residence), and Sintomi (Symptoms).

2. Takes user input: A character array richiesta with space for 20 characters is used to store the input entered by the user. The std::cin.getline function captures up to 19 characters (reserving 1 for the null terminator) and places the input into the richiesta array.

3. Echoes the input: The user input stored in richiesta is printed back to the console using std::cout << richiesta;.

What the code does not do:

• This function currently does nothing with the Paziente *scheda parameter; it is passed in but not used within the function.
• The function does not actually update or modify any of the fields of the Paziente object.
• It doesn't process or validate the user input beyond capturing and printing it.

In summary, the code displays a prompt, accepts user input about a field they want to update, and echoes their input back to them — but no actual modifications or updates occur to the Paziente structure or class in its current state.
