          int number = 42;
          Console.WriteLine(number);
      }
  }
  

• Operators: Performing arithmetic operations.

  using System;
  
  class Program {
      static void Main() {
          int a = 10;
          int b = 5;
          int sum = a + b;
          Console.WriteLine(sum);
      }
  }
  

• Control Structures: Conditional statements and loops.

  using System;
  
  class Program {
      static void Main() {
          int i = 0;
          while (i < 5) {
              Console.WriteLine(i);
              i++;
          }
      }
  }
  

• Methods: Creating and using methods.

  using System;
  
  class Program {
      static void Main() {
          GreetUser("Alice");
      }
  
      static void GreetUser(string name) {
          Console.WriteLine($"Hello, {name}!");
      }
  }
  

• Classes and Objects: Basic object-oriented programming.

  using System;
  
  class Person {
      public string Name { get; set; }
      public int Age { get; set; }
  
      public void DisplayInfo() {
          Console.WriteLine($"Name: {Name}, Age: {Age}");
      }
  }
  
  class Program {
      static void Main() {
          Person person = new Person();
          person.Name = "Bob";
          person.Age = 30;
          person.DisplayInfo();
      }
  }
