Learn C# OOP to write cleaner, modular, and scalable code by understanding classes in C#, working with objects in C#, and applying principles like data hiding, encapsulation, and inheritance.

Become a C# Programmer

This module provides an in-depth exploration of C# OOP (object-oriented programming), focusing on writing cleaner, more modular, and scalable code. We'll begin by covering the basics of classes in C# and objects in C# and progress toward advanced OOP concepts such as encapsulation, data hiding in C#, inheritance in C#, and polymorphism. Throughout, we’ll see how C# supports these OOP principles with its unique features to enhance development efficiency.

Object-Oriented Programming in C#

## Problem Statement
You have to implement a method `GetDetails()` in the **Derived Class** `Beverage`, which inherits from the `Product` class. 
* An auto-implemented property `Liters` of type `int` is declared in the `Beverage` class.
* Modify the declaration of the `Beverage` class so that it inherits from the `Product` class.

* In the implementation of `GetDetails()` method,  you must append and return the `Liters` along with the corresponding beverage's `_name` and `_price` values inherited from the base class, in the form of a string.

* We have already implemented the **Base Class** `Product` with the getters namely:
   - `GetName(int liters)` - you have to pass the liters as a parameter to get the respective name of the `Beverage`) 
  - `GetPrice(int liters)` - you have to pass the liters as a parameter to get the respective price of the `Beverage`). 

These getters return the name and price of the beverage.


### Sample Input
```c#
Beverage cola = new Beverage();
cola.Litres = 1;
```
### Sample Output
```C#
cola.GetDetails() = "Cola, 2, 1"
```

Can you Implement the Derived Class function by using the Base Class functions? A solution is placed in the solution section to help you, but we would suggest you try to solve it on your own first.
