If I were you, instead of writing (or coding) "question1", ..., "question5", I would have code an array of questions for 5 elements, and thus your code could be more compact.

My God, you´re like an angel that came to teach us C++! Thank you so much!

You are amazing, but you forgot to answer the most important question of all - what is the difference between a struct and a class... the answer is: The only difference between a struct and class in C++ is the default accessibility of member variables and methods. In a struct they are public; in a class they are private (at least per my understanding).

Most programming classes or structured college courses teach to always specify access modifiers explicitly in your code anyways, which somewhat makes the point moot to people with formal classes. But for beginners who do not take formal classes, you do have a point.

This must be the best channel for C++

These are excellent courses that I am using as a refresher as I mostly use C for embedded code but love C++.

One thing i have learned is not to use single letter variables. The reason is that it is sooo tedious to search for a single-letter variable in a larger program. Just using 'ps' as 'person' instead of 'p' can save you from a lot of grief. Loop-Iteration-vars like 'i' is an exception, from that recommendation.

My only criticism is that you show the first example of code and make it seem like it’s going to be too much to maintain if there were thousands of phones…but then you go on and add way more code and I didn’t feel like I understood why your strategy of a structure and functions somehow produced less code. Also, as a beginner, I tend to run into a lot more questions/problems/quizzes/tests on code that involves math/logic and I’ve rarely encountered strings. I understand that strings made it easier to explain, but I’d love to see some math examples! Great job
