add to the c# code :
1. The user shall be able to enter an unlimited number of recipes.
2. The user shall be able to enter a name for each recipe.
3. The software shall display a list of all the recipes to the user in alphabetical order by name.
4. The user can choose which recipe to display from the list.
5. For each ingredient, the user shall additionally be able to enter:
a. The number of calories, and
b. The food group that the ingredient belongs to.
6. The user shall be able to request that the recipe is scaled by a factor of 0.5 (half), 2
(double), or 3 (triple). All the ingredient quantities shall be changed accordingly when the
recipe is displayed. For example, one tablespoon of sugar will become two tablespoons of
sugar if the factor is 2.
7. The user can request that the quantities be reset to the original values.
8. The user shall be able to clear all the data to enter a new recipe.
9. The software shall calculate and display the total calories of all the ingredients in a recipe.
10. The software shall notify the user when the total calories of a recipe exceed 300.
11. You are required to use internationally acceptable coding standards. Include
comprehensive comments explaining variable names, methods, and the logic of
programming code.
12. You are required to use classes.
13. You must use generic collections to store the recipes, ingredients, and steps, and no longer
arrays.
14. You are required to use a delegate to notify the user when a recipe exceeds 300 calories.
