  5. structs are value types that can contain data and functions • structs are value types and do not require heap allocation. • structs directly store their data in the struct, classes store a reference to a dynamically allocated object. • structs are useful for small data structures • structs can affect performance • Constructors are invoked with the new operator, but that does not allocate memory on the heap • A struct constructor simply returns the struct value itself (typically in a temporary location on the stack), and this value is then copied as necessary #1: When to Use a struct vs Class

  6. With classes, multiple variables may have a reference to the same object • It is possible for operations on one variable to affect the object referenced by the other variable. • With structs, the variables each have their own copy of the data, and it is not possible for operations on one to affect the other. • structs do not support user-specified inheritance, and they implicitly inherit from type object #1: When to Use a struct vs Class, Cont’d
