💻 C++ Tutorial — Topic 2: Setting Up C++ (Download & Installation Guide)

You’ve learned what programming is 💡
Now let’s make your computer ready to run your first C++ program! ⚙️

🧰 Step 1: Choose Your Setup Style

You can run C++ in two easy ways:

1️⃣ Online (No Installation Needed)
2️⃣ Offline (Install an IDE or Compiler)

Let’s see both 👇

🌐 Option 1: Use an Online Compiler (Recommended for Beginners)

Perfect for learning — no setup, no downloads!
Here are a few trusted sites:

🔹 https://www.programiz.com/cpp/

🔹 https://www.onlinegdb.com/

🔹 https://www.jdoodle.com/c-online-compiler

How to Use:
1️⃣ Open the site.
2️⃣ Paste your code in the editor.
3️⃣ Click Run ▶️ and see the output below!

💡 Great for mobile users or anyone learning the basics.

💻 Option 2: Install a C++ IDE (Offline Setup)

If you want to code like a pro — install an IDE (Integrated Development Environment).

Choose one based on your operating system:

🪟 Windows Users

✅ Option 1: Code::Blocks (Beginner Friendly)

Visit: https://www.codeblocks.org/downloads/

Download “codeblocks-20.03mingw-setup.exe” (includes compiler)

Install → Open → Create a new file → Write your code → Press F9 to run

✅ Option 2: Dev-C++

Download from: https://sourceforge.net/projects/orwelldevcpp/

Simple and lightweight!

🍎 Mac Users

Use Xcode (from the App Store):

Search for “Xcode” → Install

Open Terminal → Run:

g++ hello.cpp -o hello/hello

You’re good to go! 🎉

🐧 Linux Users

C++ is often preinstalled!
To check, open your Terminal and type:
g++ --version

If not installed, run:

sudo apt install g++

Then compile your code:

g++ hello.cpp -o hello/hello

🧠 Tip:

Always save your file with .cpp extension, e.g.,
📄 hello.cpp

That tells the computer it’s a C++ file.

🚀 You’re Ready!

Now your system can compile and run C++ programs.
Let’s move on to writing and understanding your first lines of code in the next topic!
