KEYWORDS

• STRUCTURE (Struct)--> a data type that allows the creation of a single variable that can store different types of related data

In C#, a structure, also known as struct, is a data type that falls into the 'value type' category. It allows you to create a single variable that can store different types of related data. To create one of these structures, we use a keyword called 'struct'.

DEFINE A STRUCTURE

OBJECTIVE: Create a structure to store data on movies.

The data to be stored are: -> Title -> Genre -> Year Released

struct Movies
{
    public string title;
    public string genre;
    public int yearReleased;
}

USE OF A STRUCTURE

OBJECTIVE: Use the struct Movies to add 3 movies to the movie database and define the necessary data.

public class movieDatabase
{
    private void Start()
    {
        Movies movie1;
        Movies movie2;
        Movies movie3;
        
        movie1.title = "Aladdin";
        movie1.genre = "Animation";
        movie1.yearReleased = "1992";
        
        movie2.title = "Pearl Harbor";
        movie2.genre = "War";
        movie2.yearReleased = "2001";
        
        movie3.title = "The Notebook";
        movie3.genre = "Romantic";
        movie3.yearReleased = "2004";
    }
}

CONSTRUCTORS IN STRUCTURE

A struct cannot contain a parameterless constructor, it can only contain parameterized constructors or static constructors.

To use constructors within a structure you must include ALL members of the struct in the parameterized constructor and assign parameters to members.

OBJECTIVE: With the use of constructors, add 3 more movies to the database.

ADD CONSTRUCTORS TO STRUCT

struct Movies
{
    public string title;
    public string genre;
    public int yearReleased;
    
    public Movies(string title, string genre, int yearReleased)
    {
        this.title = title;
        this.genre = genre;
        this.yearReleased = yearReleased;
    }
}

ACCESS CONSTRUCTORS WITHIN CLASS

public class movieDatabase
{
    private void Start()
    {
        Movies movie4 = new Movies("The Matrix", "Sci-Fi", 1999);
        Movies movie5 = new Movies("John Wick", "Action", 2014);
        Movies movie6 = new Movies("Se7en", "Mystery", 1995);  
    }
}
