using System;
namespace RecipeApp
{
// The code defines a class called Recipe with three properties: Ingredients, OriginalIngredients, and Steps.
// It also includes three methods: DisplayRecipe(), ScaleRecipe(double factor), and ResetRecipe().

class Recipe
{
public string[] Ingredients { get; set; }
public string[] OriginalIngredients { get; set; }
public string[] Steps { get; set; }

//The DisplayRecipe() method is called to display the ingredients and steps of the recipe.

public void DisplayRecipe()
{
Console.WriteLine("Ingredients:");
foreach (string ingredient in Ingredients)
{
Console.WriteLine("- " + ingredient);
}

Console.WriteLine("\nSteps:");
for (int i = 0; i < Steps.Length; i++)
{
Console.WriteLine((i + 1) + ". " + Steps[i]);
}
}

public void ScaleRecipe(double factor)
{
Console.WriteLine("\nScaled Recipe:");
foreach (string ingredient in Ingredients)
{
string[] parts = ingredient.Split(' ');
double quantity = Convert.ToDouble(parts[0]) * factor;
Console.WriteLine("- " + quantity + " " + parts[1] + " " + parts[2]);
}
}

public void ResetRecipe()
{
Ingredients = OriginalIngredients;
}
}

class Program
{
//The Main() method is the entry point of the program.
//It creates an instance of the Recipe class and prompts the user to input the number of ingredients and steps.
static void Main(string[] args)
{
Recipe recipe = new Recipe();

Console.Write("Enter the number of ingredients: ");
int numIngredients = Convert.ToInt32(Console.ReadLine());
string[] ingredients = new string[numIngredients];
for (int i = 0; i < numIngredients; i++)
{
Console.Write("Enter ingredient " + (i + 1) + ": ");
string ingredient = Console.ReadLine();

Console.Write("Enter the quantity " + (i + 1) + ": ");
string quantity = Console.ReadLine();

Console.Write("Enter the measurement " + (i + 1) + " (cup, Kg, ml, L, g): ");
string measurement = Console.ReadLine();

ingredients[i] = quantity + " " + measurement + " " + ingredient;
}
recipe.Ingredients = ingredients;
recipe.OriginalIngredients = ingredients;

Console.Write("\nEnter the number of steps: ");
int numSteps = Convert.ToInt32(Console.ReadLine());
string[] steps = new string[numSteps];
for (int i = 0; i < numSteps; i++)
{
Console.Write("Enter step " + (i + 1) + ": ");
steps[i] = Console.ReadLine();
}
recipe.Steps = steps;

recipe.DisplayRecipe();

//The user is then prompted to enter a scaling factor (0.5, 2, or 3)
//to scale the recipe by multiplying the quantities of each ingredient by the factor.
//The ScaleRecipe() method is called with the factor as an argument to display the scaled recipe.

Console.Write("\nEnter a scaling factor (0.5, 2, or 3): ");
double factor = Convert.ToDouble(Console.ReadLine());
recipe.ScaleRecipe(factor);

// The user is given the option to reset the recipe to its original scale by inputting "Y".
// If selected, the ResetRecipe() method is called to revert the ingredients property back to the original ingredients input.
Console.WriteLine("\nDo you want to reset to the original scale? (Y/N)");
string resetInput = Console.ReadLine();
if (resetInput.ToLower() == "y")
{
recipe.ResetRecipe();
Console.WriteLine("\nRecipe has been reset to the original scale:");
recipe.DisplayRecipe();
}

Console.WriteLine("\nPress any key to clear recipe and enter a new one...");
Console.ReadKey();
Console.Clear();

Main(args);
}
}
}

keep the original code and just add to the c# code for it to have a menu
1. add a recipe (if the user selects 1 they should be able to do the DisplayRecipe() method
2. scale recipe (if the user picks 2 this they should be able to do the ScaleRecipe() method and it should display the new scaled recipe)
3. set to original recipe (if user selcts 3 they should be able to do the ResetRecipe() method and it should display the original recipe before it was scaled)
4. exit (if the user selects 4 they should be able to stop running the program)

Here's the updated C# code with a menu added for user interaction:

```csharp
using System;

namespace RecipeApp
{
class Recipe
{
public string[] Ingredients { get; set; }
public string[] OriginalIngredients { get; set; }
public string[] Steps { get; set; }

public void DisplayRecipe()
{
Console.WriteLine("Ingredients:");
foreach (string ingredient in Ingredients)
{
Console.WriteLine("- " + ingredient);
}

Console.WriteLine("\nSteps:");
for (int i = 0; i < Steps.Length; i++)
{
Console.WriteLine((i + 1) + ". " + Steps[i]);
}
}

public void ScaleRecipe(double factor)
{
Console.WriteLine("\nScaled Recipe:");
foreach (string ingredient in Ingredients)
{
string[] parts = ingredient.Split(' ');
double quantity = Convert.ToDouble(parts[0]) * factor;
Console.WriteLine("- " + quantity + " " + parts[1] + " " + parts[2]);
}
}

public void ResetRecipe()
{
Ingredients = OriginalIngredients;
}
}

class Program
{
static void Main(string[] args)
{
Recipe recipe = new Recipe();

bool running = true;
while (running)
{
Console.WriteLine("\nMENU:");
Console.WriteLine("1. Add a Recipe");
Console.WriteLine("2. Scale Recipe");
Console.WriteLine("3. Set to Original Recipe");
Console.WriteLine("4. Exit");
Console.Write("Select an option: ");
int option = Convert.ToInt32(Console.ReadLine());

switch (option)
{
case 1:
Console.Write("Enter the number of ingredients: ");
int numIngredients = Convert.ToInt32(Console.ReadLine());
string[] ingredients = new string[numIngredients];
for (int i = 0; i < numIngredients; i++)
{
Console.Write("Enter ingredient " + (i + 1) + ": ");
string ingredient = Console.ReadLine();

Console.Write("Enter the quantity " + (i + 1) + ": ");
string quantity = Console.ReadLine();

Console.Write("Enter the measurement " + (i + 1) + " (cup, Kg, ml, L, g): ");
string measurement = Console.ReadLine();

ingredients[i] = quantity + " " + measurement + " " + ingredient;
}
recipe.Ingredients = ingredients;
recipe.OriginalIngredients = ingredients;

Console.Write("\nEnter the number of steps: ");
int numSteps = Convert.ToInt32(Console.ReadLine());
string[] steps = new string[numSteps];
for (int i = 0; i < numSteps; i++)
{
Console.Write("Enter step " + (i + 1) + ": ");
steps[i] = Console.ReadLine();
}
recipe.Steps = steps;

break;

case 2:
Console.Write("\nEnter a scaling factor (0.5, 2, or 3): ");
double factor = Convert.ToDouble(Console.ReadLine());
recipe.ScaleRecipe(factor);
break;

case 3:
recipe.ResetRecipe();
Console.WriteLine("\nRecipe has been reset to the original scale:");
recipe.DisplayRecipe();
break;

case 4:
running = false;
break;

default:
Console.WriteLine("Invalid option. Please try again.");
break;
}
}
}
}
}
```

This updated code now includes a menu with options for the user to add a recipe, scale the recipe, set it back to the original recipe, or exit the program. Depending on the user's selection, the corresponding method will be executed.
