Die Strukturen in Golang sind benutzerdefinierte Typen, die es uns ermöglichen, eine Gruppe verschiedener Elemente in einer Einheit zu erstellen. Jede reale Entität, die eine Gruppe von Attributen oder Feldern hat, kann als Struktur dargestellt werden.
In Go language, it is allowed to create anonymous structures. Anonymous structures are structures without names. They are very useful when you need to create a one-time usable structure. You can create an anonymous structure using the following syntax:
variable_name := struct{ // fields }{// Field_values}
Let's use an example to discuss this concept:
//Concept of anonymous structure package main import "fmt" func main() { // Create and initialize an anonymous structure Element := struct { name string branch string language string Particles int }{ name: "Zhan San", branch: "Development Department", language: "C"++" Particles: 498, } //Display anonymous structure fmt.Println(Element) }
Output:
{Zhan San Development Department C++ 498}
In Go structures, it is allowed to create anonymous fields. Anonymous fields are those that do not contain any names. You just need to mention the field type, and Go will automatically use the type as the field name. You can create an anonymous field in the structure using the following syntax:
type struct_name struct{ int bool float64 }
Important Note:
In a structure, it is not allowed to create two or more fields of the same type, as shown below:
type student struct{ int int }
If you try to do this, the compiler will throw an error.
It is allowed to combine anonymous fields with named fields, as shown below:
type student struct{ name int price int string }
Let's use an example to discuss the concept of anonymous fields:
package main import "fmt" //Create an anonymous field in the structure type student struct { int string float64 } // Main function func main() { // Assign values to the fields of the anonymous, student structure value := student{123, "Bud", 8900.23} fmt.Println("Number of Admissions: ", value.int) fmt.Println("Student Name: ", value.string) fmt.Println("Package Price: ", value.float)64) }
Output:
Number of Admissions: : 123 Student Name: Bud Paketpreis : 8900.23
