What is the proper syntax for access a member struct variable? I'm currently trying like this:
struct one {
var name:String = "Ric"
var address:String = "Lee"
}
one.name
But the last line produces the error:
'one.Type' does not have a member named 'name'
How can I access the variable on my struct?
Array elements are accessed using the Subscript variable, Similarly Structure members are accessed using dot [.] operator. Structure written inside another structure is called as nesting of two structures.
Syntax to Define a Structure in CstructName: This is the name of the structure which is specified after the keyword struct. data_Type: The data type indicates the type of the data members of the structure. A structure can have data members of different data types.
A "structure declaration" names a type and specifies a sequence of variable values (called "members" or "fields" of the structure) that can have different types. An optional identifier, called a "tag," gives the name of the structure type and can be used in subsequent references to the structure type.
Structures (also called structs) are a way to group several related variables into one place. Each variable in the structure is known as a member of the structure. Unlike an array, a structure can contain many different data types (int, float, char, etc.).
It looks like you defined a struct, but didn't create an instance of it. If you create an instance, you can access its name and address properties.
struct one {
var name: String = "Ric"
var address: String = "Lee"
}
var x = one()
x.name
It may be confusing because you can set default values in the definition, which may make it look like you are instantiating something.
