explain this whole code line by line.

Answer 1

The code provided is a C# console application that allows a user to input a recipe with ingredients and steps, display the recipe, scale the recipe by a factor, and reset the recipe to its original scale.

1. 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().

2. 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.

3. The user is then prompted to enter each ingredient with its quantity and measurement unit, which are stored in an array of strings called ingredients.

4. The user is similarly prompted to input each step of the recipe, which are stored in an array of strings called steps.

5. The ingredients and steps arrays are assigned to the respective properties of the recipe instance.

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

7. 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.

8. 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.

9. The program then prompts the user to continue entering new recipes by pressing any key, clearing the console, and calling the Main() method recursively.

Overall, this code demonstrates how to create a recipe object, input ingredients and steps, display the recipe, scale the recipe, and reset it to its original scale in a console application.
