Structure(s) or 'structs'...
What is a structure or struct? This term and programming development construct, refers to a user-defined, custom, value-type, consisting of other types. It is taken from the root meaning from the programming language called keyword upon to enact and create it. As with other value types, these user-defined instances types, are typically stored on the stack, containing their data directly (not stored somewhere else, separately) Structures behave very similarly to classes in their very nature. A composite of other types, to make it come ‘compatible’, readily accessible, inter-operable to an extent.
Good for use for repetition over a fixed range, or a cycle. Conversions can also be done with these, but more efficient than classes in general. Criteria for structure types include: (i) single value representation logically (ii) instance size less than 16 bytes (iii) not cast to a reference type/conversion (iv) not frequently altered after being created.
