Learn how to install the GCC compiler and use it to compile and run C++ programs on your Raspberry Pi. This article will walk you through the process from start to finish, providing clear instructions and helpful tips along the way.

1. Open a terminal window by clicking on the “Terminal” icon in the top menu or pressing Ctrl+Alt+T.
2. Update the package lists with the following command:

   sudo apt update
   

3. Install the GCC compiler with this command:

   sudo apt install g++
   

4. Verify that the installation was successful by checking the version of the compiler:

   g++ --version
   

   This should output something like g++ (Raspbian 8.3.0-6+rpi1) 8.3.0.

Now you have the GCC compiler installed on your Raspberry Pi, and can start writing and compiling C++ programs! Here’s a quick example to get started:

1. Create a new file called hello.cpp using your favorite text editor (e.g., nano):

   nano hello.cpp
   

2. Add the following code to the file and save it:

   #include <iostream>
   
   int main() {
       std::cout << "Hello, world!" << std::endl;
       return 0;
   }
   

3. Compile the program using g++:

   g++ hello.cpp -o hello
   

4. Run the compiled program:

   ./hello
   

   This should output Hello, world! in your terminal window. Congratulations, you’ve just written and run your first C++ program on a Raspberry Pi!

If you encounter any issues during installation or compilation, make sure that your Raspberry Pi is connected to the internet and check for updates using:

sudo apt upgrade

Also, if you prefer an integrated development environment (IDE) to write and run C++ programs on your Raspberry Pi, there are several options available, such as Code::Blocks or Eclipse CDT. You can install them by following the instructions provided in their respective documentation.
