Although Arduino's programming language is based on C++, you won't be able to use all of its commands. But, you can still use objects in Arduino's IDE, which are a fundamental aspect of C++.

That means you’ve got power. In Arduino IDE, navigate to File > Examples > Basics > Blink, and open the file. You’ll see code that might not make sense now, but it will.

The Arduino IDE provides a sample sketch with a simple program outline in a text window when you first open it. There are also a vast array of code samples under the File->Examples submenu item.
