🚀 Getting Started

🔧 Requirements

• C++17 or above
• C++ compiler (e.g. g++, clang++, MSVC)

📥 Installation

Clone the repository:

git clone https://github.com/AbdoJoker99/Cpp

🛠️ Installing MSYS2 and GCC (Windows)

1. Download MSYS2 from https://www.msys2.org

2. Install and open the MSYS2 terminal

3. Update the package database and core system packages:

   pacman -Syu

   🔁 Restart the terminal when prompted, then continue:

   pacman -Su

4. Install GCC and Build Tools:

   pacman -S mingw-w64-ucrt-x86_64-gcc

5. [Recommended Fix] GPG Key Issue (if package installation fails):

   If you encounter an error related to invalid or missing GPG keys when installing packages, run:

   pacman -S gnupg

   Then initialize the keyring with:

   pacman-key --init
   pacman-key --populate msys2

6. Use the MSYS2 MinGW UCRT 64-bit terminal to compile your code:

   g++ -std=c++17 -o program your_code.cpp
   ./program
