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
• 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
