When to Use a struct vs Class, Cont’d

=> 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 bject.
=> 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 
=> 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
