On the Windows platform navigate to the Start | All Programs | CodeBlocks | CodeBlocks menu options to launch Code::Blocks. Alternatively you may double-click on the shortcut displayed on the desktop to launch Code::Blocks, as in the following screenshot:

On Linux navigate to Applications | Programming | Code::Blocks IDE menu options to run Code::Blocks. Please note that in subsequent chapters of this book we'll limit our discussion mostly to the Windows platform.

The following screenshot shows main window of Code::Blocks. Annotated portions highlight different User Interface (UI) components:

Now, let us understand more about different UI components:
