Introduction to C#
What is C#? C# (pronounced "C sharp") is a general-purpose, modern programming language developed by Microsoft as part of its .NET framework. It was first introduced in 2000 and has since become one of the primary languages used for building Windows desktop applications, web applications, and other software solutions on the Microsoft platform. C# is an object-oriented programming (OOP) language that combines the power and flexibility of C++ with the simplicity and ease of use of Visual Basic. It is designed to be a simple, efficient, and type-safe language that enables developers to create robust and scalable applications. Some key features of C# include: • Object-Oriented Programming (OOP): C# supports fundamental OOP concepts such as encapsulation, inheritance, and polymorphism, allowing developers to create modular and reusable code. • Type Safety: C# enforces strict type checking, which helps prevent errors and promotes code reliability. • Garbage Collection: C# includes automatic memory management through a garbage collector, which frees developers from managing memory manually. • Language Integration: C# integrates seamlessly with other .NET languages, allowing developers to leverage existing libraries and components. • Rich Standard Library: C# provides a comprehensive standard library that offers a wide range of functionality for common tasks, including input/output operations, network programming, and database access. • Platform Independence: While C# was initially designed for Windows development, it has expanded its reach through cross-platform frameworks like .NET Core and Xamarin, enabling developers to build applications that run on multiple operating systems, including Windows, macOS, and Linux. Overall, C# is a versatile language that empowers developers to build a variety of software applications, from desktop applications and web services to mobile apps and games, using the .NET framework.

Classes and objects
Classes and objects In C#, classes and objects are fundamental concepts of object-oriented programming (OOP). They provide a way to define the structure and behavior of objects, which are instances of classes. Here's an overview of classes and objects in C#:

Data types and variables

In C#, data types are used to define the type and size of data that a variable can hold. Variables, on the other hand, are used to store and manipulate data in a program. Here are some commonly used data types and how to declare variables in C#:

  1. Numeric Data Types:
  • Int: Used to store whole numbers. Example: int age = 25;
  • Float: Used to store single-precision floating-point numbers. Example: float price = 9.99f;
  • Double: Used to store double-precision floating-point numbers. Example: double pi = 3.14159;
  • Decimal: Used to store decimal numbers with high precision. Example: decimal salary = 50000.50m;
  1. Boolean Data Type:
  • Bool: Used to store true/false values. Example: bool isComplete = true;
  1. Character Data Type:
  • Char: Used to store a single character. Example: char grade = ‘A’;
  1. String Data Type:
  • String: Used to store a sequence of characters. Example: string name = “John Smith”;
  1. Date and Time Data Types:
  • DateTime: Used to store date and time values. Example: DateTime currentDate = DateTime.Now;
  1. Arrays:

Arrays allow you to store multiple values of the same data type in a single variable. Example: int[] numbers = { 1, 2, 3, 4, 5 };

  1. Variables Declaration:

  • To declare a variable, you specify the data type followed by the variable name. Example: int age;
  • You can also assign an initial value to the variable during declaration. Example: int age = 25;
  1. Variable Assignment and Modification:
  • Once a variable is declared, you can assign a value to it using the assignment operator (=). Example: age = 30;
  • You can modify the value of a variable by assigning a new value to it. Example: age = age + 1;
  1. Constants:
  • Constants are variables whose value cannot be changed once assigned. Example: const double pi = 3.14159;
  1. variable Naming :Variable names must start with a letter or underscore and can contain letters, numbers, and underscores. Example: int student Count;
