Part $2$ Advanced C# Features $($Marks: $100)$ Learning Units $1$ to $3$ At the end of this specific part, students should be able to:

$$ Use a generic collection to solve a programming problem.

$$ Use delegates to solve a programming problem.

You will continue working on the application created in part $1.$ Implement the feedback provided by your lecturer on part $1$ before continuing with part $2.$ Marks will be awarded for this $(10\%).$

The application must still perform all the functions from part $1,$ with the following features added:

$1.$ 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.

$6.$ The software shall calculate and display the total calories of all the ingredients in a recipe.

$7.$ The software shall notify the user when the total calories of a recipe exceed $300.$

Non$-$functional requirements:

$8.$ You are required to use internationally acceptable coding standards. Include comprehensive comments explaining variable names, methods, and the logic of programming code.

$9.$ You are required to use classes.

$10.$ You must use generic collections to store the recipes, ingredients, steps, and no longer arrays. $11.$ You are required to use a delegate to notify the user when a recipe exceeds $300$ calories.

$12.$ You are required to create a unit test to test the total calory calculation.
