Introduction to C#

• History and significance of the C# programming language.
• Structure of a C# program.
• Compiling and executing C# programs.

Variables and Data Types

• Declaring and initializing variables.
• Fundamental data types (int, float, double, char, bool).
• Using modifiers (signed, unsigned, short, long).

Input and Output

• Using Console for console input/output.
• Formatting output using format specifiers.
• Working with standard input/output streams.

Operators and Expressions

• Arithmetic operators (+, -, *, /, %).
• Relational and logical operators (>, <, ==, &&, ||).
• Bitwise operators (&, |, ~, ^).

Control Flow

• Conditional statements (if-else, switch-case).
• Looping constructs (for, while, do-while).
• Using break and continue statements.

Arrays and Collections

• Declaring and accessing arrays.
• Working with multidimensional arrays.
• Using built-in collections like lists, dictionaries, and queues.

Classes and Objects

• Creating classes and objects.
• Defining and accessing class members (fields, properties, methods).
• Constructors and object initialization.

Inheritance and Polymorphism

• Inheriting from base classes.
• Method overriding and virtual/override keywords.
• Abstract classes and interfaces.

Exception Handling

• Handling exceptions using try-catch blocks.
• Throwing and catching exceptions.
• Creating custom exception classes.

Generics

• Using generic classes, methods, and interfaces.
• Type constraints and generic type parameters.
• Creating reusable generic code.

File Handling and I/O

• Working with files (reading, writing, appending).
• Streams and stream readers/writers.
• Serializing and deserializing objects.

Delegates and Events

• Understanding delegates and events.
• Creating and invoking delegates.
• Subscribing to and raising events.

LINQ (Language Integrated Query)

• Querying and manipulating data using LINQ.
• Working with LINQ to Objects and LINQ to SQL.
• Using lambda expressions.

Advanced Topics (optional)

• Asynchronous programming with async/await.
