You can learn about using the Oracle Developer Studio IDE by reading the IDE's integrated help, which you can access through the IDE's Help menu or by pressing the F1 key. Many dialog boxes also have a Help button for information about how to use the dialog box.
The tutorials on the NetBeans IDE C/C++ Learning Trail can also be helpful for learning how to use the Oracle Developer Studio IDE, although there are some differences between the user interfaces and features. In particular, NetBeans documentation about debugging does not apply to Oracle Developer Studio IDE.
