What are Structures?
- A structure or struct is a user-defined type to store a collection of different fields into a single field.
- Any real-world entity which has some set of properties/fields can be represented as a struct.
- For Example, an address has a name, street, city, state, pincode. It makes sense to group these three properties into a single structure.
How to Declare Structure?
type Address struct {
name string
street string
city string
state string
pincode int
}
OR
type Address struct {
name ,street ,city , state string
pincode int
}To Define a Structure
var a Address
To Initialize a variable of a struct type
var a = Address{"Amit","Baner","Pune","Maharashtra",411045}Note:
- Always pass the field values in the same order in which they are declared in which they are declared in the struct.
- Go also supports the name:value syntax for initializing a struct.
var a =Address{Name:"Vikas",street:"RamNagar",state:"Bihar",pincode:841406}How to access fields of a struct?
- To access individual fields of a struct, use dot(.) operator
fmt.println("Name is:",a.name)
fmt.println("city is",a.city)Thank you for reading :)
