Records

To wrap up the analysis of built-in data types, we have to discuss structured types that can store elements of different types—namely records, classes, and interfaces.

The simplest of them are records. They are actually quite similar to simple types and static arrays. As simple types, records are, as we say, statically allocated. Local variables of record type are part of a thread's stack, global variables are part of the global process memory, and records that are parts of other structured types are stored as part of the owner's memory.

The important thing that you have to remember when using records is that the compiler manages the life cycle for their fields that are themselves managed. In other words, if you declare a local variable ...
