explain this code line by line.
Sure! Here is an explanation of the code line by line:
1. `using System;`: This line includes the `System` namespace in the program which contains commonly used types such as data types, collections, and input/output.
2. `namespace RecipeApp`: Defines a namespace called `RecipeApp` to organize the code into a logical group.
3. `class Recipe`: Defines a class called `Recipe` which contains properties for Ingredients, OriginalIngredients, and Steps, as well as methods to display the recipe, scale the recipe, and reset the recipe.
4. `public string[] Ingredients { get; set; }`: Defines a public property for Ingredients that allows access to the array of ingredients.
5. `public string[] OriginalIngredients { get; set; }`: Defines a public property for OriginalIngredients to store the original set of ingredients before scaling.
6. `public string[] Steps { get; set; }`: Defines a public property for Steps to store the steps of the recipe.
7. `public void DisplayRecipe()`: Defines a method to display the ingredients and steps of the recipe.
8. `public void ScaleRecipe(double factor)`: Defines a method to scale the recipe by a given factor.
9. `public void ResetRecipe()`: Defines a method to reset the recipe to its original scale.
10. `class Program`: Defines a class called `Program` which contains the `Main` method where the program execution starts.
11. `static void Main(string[] args)`: The entry point of the program, where the `Main` method is defined.
12. `Recipe recipe = new Recipe();`: Creates an instance of the `Recipe` class to work with.
13. `Console.Write("Enter the number of ingredients: ");`: Displays a prompt to the user to enter the number of ingredients.
14. `int numIngredients = Convert.ToInt32(Console.ReadLine());`: Reads the user input for the number of ingredients and converts it to an integer.
15. `string[] ingredients = new string[numIngredients];`: Creates an array to store the ingredients entered by the user.
And so on... the explanation continues for each line of code in the program. Let me know if you would like me to continue or if you have any specific questions!
