Introduction to C++

• Fast language: Used in advanced graphics apps (Adobe, video editing) and video games.
• Middle-level language: Falls between high-level languages (Python, Java) and low-level hardware instructions.
• Learning curve: Worthwhile to master for performance benefits.

1. Text editor/IDE: VS Code, Code Blocks, etc.
2. Compiler: GCC for Windows/Linux, Clang for macOS.

Installing VS Code

1. Download from code.visualstudio.com.
2. Install, create desktop icon if you prefer.
3. Launch and install extensions: C/C++ and Code Runner.

Setting Up Compiler

Linux

• Open terminal: gcc -v to check installation.
• If not installed: sudo apt-get install build-essential.

macOS

• Open terminal: clang -v to check.
• If not installed: xcode-select --install.

Windows

1. Install MinGW-w64.
2. Open MSYS2, update with pacman -Syu.
3. Install development tools: pacman -S --needed base-devel mingw-w64-x86_64-toolchain.
