I'll create a Python-based C# teaching assistant that can explain C# concepts and provide code examples. Here's the implementation: class CSharpConcept: def __init__(self, name, description, example): self.name = name self.description = description self.example = example class CSharpConceptsDatabase: def __init__(self): self.concepts = [ CSharpConcept( "Variables", "Variables in C# are strongly typed and must be declared with a specific type.", "int age = 25;\ndouble price = 19.99;\nstring name = \"John\";" ), CSharpConcept( "Classes", "Classes are blueprints for creating objects in C#. They can contain fields, properties, methods, and events.", "public class Person {\n public string Name { get; set; }\n public int Age { get; set; }\n\n public void Greet() {\n Console.WriteLine($\"Hello, my name is {Name}\");\n }\n}" ), CSharpConcept( "Methods", "Methods are blocks of code that perform specific tasks. They can take parameters and return values.", "public int Add(int a, int b) {\n return a + b;\n}\n\n// Usage:\nint result = Add(5, 3);" ), CSharpConcept( "Loops", "C# provides several loop structures: for, while, do-while, and foreach.", "// For loop\nfor (int i = 0; i < 5; i++) {\n Console.WriteLine(i);\n}\n\n// Foreach loop\nstring[] names = {\"Alice\", \"Bob\", \"Charlie\"};\nforeach (string name in names) {\n Console.WriteLine(name);\n}" ), CSharpConcept( "Conditionals", "Conditional statements allow different code paths based on boolean conditions.", "int age = 18;\n\nif (age >= 18) {\n Console.WriteLine(\"Adult\");\n} else {\n Console.WriteLine(\"Minor\");\n}" ), CSharpConcept( "LINQ", "Language Integrated Query (LINQ) provides query capabilities directly in C#.", "List numbers = new List { 1, 2, 3, 4, 5 };\nvar evenNumbers = from num in numbers\n where num % 2 == 0\n select num;\n\nforeach (var num in evenNumbers) {\n Console.WriteLine(num);\n}" ), CSharpConcept( "Async/Await", "Asynchronous programming in C# using async and await keywords.", "public async Task FetchDataAsync() {\n HttpClient client = new HttpClient();\n string result = await client.GetStringAsync(\"https://example.com\");\n return result;\n}" ) ] def get_concept(self, name): for concept in self.concepts: if concept.name.lower() == name.lower(): return concept return None def list_concepts(self): return [concept.name for concept in self.concepts] import sys from csharp_concepts import CSharpConceptsDatabase class CSharpTeacher: def __init__(self): self.db = CSharpConceptsDatabase() def display_menu(self): print("\nC# Teaching Robot") print("----------------") print("1.
