The substructure is created using a reference to the dictionary structure SCARR for the second component. A nested structure is deep when it has at least one deep component or subcomponent. Is flat if it only contains flat components and subcomponents. The term "nested structure" must not be confused with the term "deep structure". The following figure illustrates a deep structure. Possible deep components include strings, internal tables, boxed components, data references, or object references.Ī structure that contains static or dynamic components is (formally) a A nested structure is flat or character-like, depending on the attributes of all of the components. Flat character-like structures are flat structures that contain only character-like components.

P, x, plus b, s (or structures with these types). Structures are named as follows (depending on the type of the component):Ĭomponents with flat data types, such as elementary types c, n,

It is also possible to specify values for some fields and ignore the rest. Hence firstName and lastName are assigned the zero values of string which is an empty string "" and age, salary are assigned the zero values of int which is 0.

The above program defines emp4 but it is not initialized with any value. package mainįmt.Println("First Name:", emp4.firstName) When a struct is defined and it is not explicitly initialized with any value, the fields of the struct are assigned their zero values by default.

package mainįmt.Println("First Name:", emp6.firstName)įmt.Printf("New Salary: $%d", emp6.salary)Įmp6.firstName in the above program accesses the firstName field of the emp6 struct. operator is used to access the individual fields of a struct. It makes sense to group these three properties into a single struct named Employee. It can be used in places where it makes sense to group the data into a single unit rather than having each of them as separate values.įor instance, an employee has a firstName, lastName and age. What is a struct?Ī struct is a user-defined type that represents a collection of fields.
