- C# was announced at the .NET Developers Conference in 2000.
- Anders Hejlsberg was a key contributor in the development of C#.
C++ Programming Language
- C++ builds upon the C programming language, offering more advanced capabilities.
- C++ is considered an intermediate-level language.
Programming Concepts
- Programming languages are structured, human-readable forms of communication between humans and computers.
- High-level languages use English words and/or mathematical symbols for programming.
C# Syntax and Elements
- Semicolon: Every C# statement ends with a semicolon (;).
-
using System;
: This statement imports theSystem
namespace, allowing the use of its classes, such asConsole
. -
public static void Main()
: This is the entry point for a C# console program. -
Console.WriteLine()
: This method outputs text to the console, including a new line at the end. -
Console.Write()
: This method outputs text to the console, without a new line at the end. -
{ }
: These curly braces mark the beginning and end of a block of code. -
.cs
: This is the file extension for C# files. - Blank Lines: Blank lines make code more readable and are ignored by C#.
