4.3.3. Nested structs

We may find a record which contains several data, and also that one of these data is made up of several simpler data. For example, a birth date could be formed by day, month and year. It would become a "struct" which contains another "struct":

using System;

public class Example41

{

  struct birthDate

  {

    public int  day;

    public int  month;

    public int  year;

  }

  struct personType

  {

    public string name;

    public char   initial;

    public birthDate birthday;

    public float  mark;

  }

  public static void Main()

  {

    personType person;

    person.name = "John";

    person.initial = 'J';

    person.birthday.day = 15;

    person.birthday.month = 9;

    person.mark = 7.5f;

    Console.WriteLine("{0} was born in month {1}",

      person.name, person.birthday.month);    

    }

}

Suggested exercises:

·       Expand the program of the first part of 4.3.2, so that the "length" is stored as minutes and seconds, using a nested "struct".
