Answer 1

The differences between a struct and class in C++ are:

• Members of a class are private by default, whereas members of a struct are public by default.
• Similarly, inheritance between classes is also private by default, and inheritance between structs is public by default.

But basically anywhere you use a struct you could use a class, and vice versa, so it's really up to you what to use. Conventionally, when you have methods, it is more common to use a class, and when you only have data, structs are more commonly used.

I would say that if you want all the data members to be public, and you have no methods, then use a struct. Otherwise use a class. But that's just personal preference.
