fix the system.FormatException on the 31st line to allow for "cup" to be entered
To fix the System.FormatException on line 31 to allow for "cup" to be entered, you can modify the way you parse the ingredient input. You can split the input by space and then check if the last part is "cup" before converting the quantity to double. Here's the updated code:
```csharp
using System;
namespace RecipeApp
{
class Recipe
{
public string[] Ingredients { 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(' ');
if (parts[2] == "cup")
{
double quantity = Convert.ToDouble(parts[0].Replace(".", ", ")) * factor;
Console.WriteLine("- " + quantity + " " + parts[1] + " " + parts[2]);
}
else
{
double quantity = Convert.ToDouble(parts[0]) * factor;
Console.WriteLine("- " + quantity + " " + parts[1] + " " + parts[2]);
}
}
}
}
class Program
{
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) + ": ");
ingredients[i] = Console.ReadLine();
}
recipe.Ingredients = 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();
Console.Write("\nEnter a scaling factor (0.5, 2, or 3): ");
double factor = Convert.ToDouble(Console.ReadLine());
recipe.ScaleRecipe(factor);
Console.WriteLine("\nPress any key to clear recipe and enter a new one...");
Console.ReadKey();
Console.Clear();
Main(args);
}
}
}
```
With this modification, the code will now check if the last part of the ingredient is "cup" before converting the quantity to double.
