Question

At the end of this specific part, students should be able to: -

Write a consoleprogram that requires user input.
- Apply string manipulation to solve a programming problem.
- Use automatic properties to solve a programming problem.
For this portfolio of evidence, you must store your source code in a GitHub repository. Make regular commits with descriptive commit comments. Marks will be awarded for this (5\%), but more importantly, it will help to keep your code safe.
Using C\# and Visual Studio, design and implement a standalone command line application that fulfils the following requirements:
1. The user shall be able to enter the details for a single recipe:
a. The number of ingredients.
b. For each ingredient: the name, quantity, and unit of measurement. For example, one tablespoon of sugar.
c. The number of steps.
d. For each step: a description of what the user should do.
2. The software shall display the full recipe, including the ingredients and steps, in a neat format to the user. 3. 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, our one tablespoon of sugar will become two tablespoons of sugar if the factor is 2 .
4. The user can request that the quantities be reset to the original values.
5. The user shall be able to clear all the data to enter a new recipe.
6. The software shall not persist the user data between runs. The data shall only be stored in memory while the software is running.
Non-functional requirements:
1. You are required to use internationally acceptable coding standards. Include comprehensive comments explaining variable names, methods, and the logic of programming code.
2. You are required to use classes.
3. Store the ingredients and steps in arrays

Answer 1

To design and implement a standalone command line application that fulfills the given requirements, a student can use C# and Visual Studio. The solution involves creating a recipe class, arrays for ingredients and steps, and methods to handle user input and display the recipe. It's important to follow coding standards and not persist user data between runs.

Step-by-step explanation:

Design and Implementation

To design and implement a standalone command line application that fulfills the given requirements, you can use C# and Visual Studio. Here are the steps to follow:

1. Create a class to represent a recipe that will store the details of the ingredients and steps.
2. Create an array to store the ingredients, where each element of the array represents the name, quantity, and unit of measurement.
3. Create another array to store the steps, where each element of the array represents a description of what the user should do.
4. Create methods to allow the user to enter the recipe details, display the full recipe, scale the recipe, reset the quantities, and clear the data.
5. Implement the logic for scaling the recipe by adjusting the ingredient quantities based on the scaling factor entered by the user.
6. Make use of console input and output to interact with the user.

Remember to use internationally acceptable coding standards and provide comprehensive comments explaining variable names, methods, and the logic of your code. Store the ingredients and steps in arrays and ensure that the user data is not persisted between runs by only storing it in memory while the software is running.
