“Getting Started with C++: A Comprehensive Guide from Basics to Advanced”

1. Introduction

1.1. What is C++?

• C++ is a high-level programming language developed by Bjarne Stroustrup.
• It is an extension of the C language with added object-oriented (OOP) features.
• General-purpose, performance-oriented, and allows for low-level programming.
• Open source with a broad range of applications.

1.2. Applications of C++

• System Software: Operating systems, compilers.
• Game Development: Unreal Engine.
• Desktop Applications: GUI applications.
• Embedded Systems: Hardware control.
• Artificial Intelligence and Scientific Computing: Performance-critical applications.

2. Installing and Setting Up C++

2.1. Downloading and Installing C++

• C++ Compilers: GCC, Clang, MSVC.
• GCC: GCC Download and Installation
• Clang: Clang Download and Installation
• MSVC: Visual Studio

2.2. C++ IDEs and Editors

• Visual Studio: A powerful IDE, especially for Windows.
• CLion: A professional IDE from JetBrains.
• Code::Blocks: A lightweight and open-source IDE.
