1. Programming Basics for Raspberry Pi

This guide introduces the essentials of C++ programming on the Raspberry Pi, focusing on setup and your first program.

Introduction to C++ on Raspberry Pi

C++ is an excellent choice for Raspberry Pi projects that require:

  • High performance and low-level hardware access
  • Direct control of GPIO pins and hardware
  • Memory-efficient applications
  • Real-time processing capabilities

The Raspberry Pi supports modern C++ standards (C++11, C++14, C++17) through the GNU C++ compiler (g++).

Setting Up Your Development Environment

Update your system and install essential development tools:

1
2
sudo apt update
sudo apt install build-essential

This installs: - g++ - The GNU C++ compiler - make - The build automation tool - Other essential build tools

Creating Your First C++ Program

Create a new file called hello.cpp:

1
2
3
4
5
6
#include <iostream>

int main() {
    std::cout << "Hello, Raspberry Pi!" << std::endl;
    return 0;
}

Compile and Run

Compile your program using g++:

1
2
g++ -o hello hello.cpp
./hello

You should see the output Hello, Raspberry Pi! displayed in your terminal.
