Editing C syntax (section)

====Structures====
Structures and [[Union type|unions]] in C are defined as data containers consisting of a sequence of named members of various types. They are similar to records in other programming languages. The members of a structure are stored in consecutive locations in memory, although the compiler is allowed to insert padding between or after members (but not before the first member) for efficiency or as padding required for proper [[data structure alignment|alignment]] by the target architecture. The size of a structure is equal to the sum of the sizes of its members, plus the size of the padding.
