Class vs Struct for data only?

Question

Is there any advantage over using a class over a struct in cases such as these? (note: it will only hold variables, there will never be functions)

class Foo         


        

Answer 1

If the contents of the type have no memory allocation issues (such as plain int), then using struct is fine if that's the way you want to go and you've made a conscious decision about it that you can justify to those who use your code. However, if any of the members is a pointer type, then you need to think hard about the memory management issues. It may still be OK to use a struct, but you are much more likely to need a destructor, and some constructors, and so on. At that point, you want a class.
