CSharp – Structure
A data structure is a group of data elements grouped together under one name. These data elements, known as members, can have different types and different lengths.
Notice that:
– structures do not support inheritance
– structures cannot have default constructor
using System; namespace ConsoleApplication1 { struct Books { public string title; public string author; public string subject; public int book_id; }; public class testStructure { public static void Main(string[] args) { Books Book1; /* Declare Book1 of type Book */ Books Book2; /* Declare Book2 of type Book */ /* book 1 specification */ Book1.title = "C Programming"; Book1.author = "Nuha Ali"; Book1.subject = "C Programming Tutorial"; Book1.book_id = 6495407; /* book 2 specification */ Book2.title = "Telecom Billing"; Book2.author = "Zara Ali"; Book2.subject = "Telecom Billing Tutorial"; Book2.book_id = 6495700; /* print Book1 info */ Console.WriteLine("Book 1 title : {0}", Book1.title); Console.WriteLine("Book 1 author : {0}", Book1.author); Console.WriteLine("Book 1 subject : {0}", Book1.subject); Console.WriteLine("Book 1 book_id :{0}", Book1.book_id); /* print Book2 info */ Console.WriteLine("Book 2 title : {0}", Book2.title); Console.WriteLine("Book 2 author : {0}", Book2.author); Console.WriteLine("Book 2 subject : {0}", Book2.subject); Console.WriteLine("Book 2 book_id : {0}", Book2.book_id); Console.ReadKey(); } // END Main } // END testStructure }
The result is:
Book 1 title : C Programming
Book 1 author : Nuha Ali
Book 1 subject : C Programming Tutorial
Book 1 book_id : 6495407
Book 2 title : Telecom Billing
Book 2 author : Zara Ali
Book 2 subject : Telecom Billing Tutorial
Book 2 book_id : 6495700
