🚀 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)

Download MSYS2 from https://www.msys2.org
Install and open the MSYS2 terminal
Update the package database and core system packages:
```
pacman -Syu
```
🔁 Restart the terminal when prompted, then continue:
```
pacman -Su
```
Install GCC and Build Tools:
```
pacman -S mingw-w64-ucrt-x86_64-gcc
```
[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
```
Use the MSYS2 MinGW UCRT 64-bit terminal to compile your code:
```
g++ -std=c++17 -o program your_code.cpp
./program
```
