Safari Books Online is a digital library providing on-demand subscription access to thousands of learning resources.
One more thing is worth mentioning before we head back to functionville. Your Mac comes with an incredible built-in resource, just perfect for experimenting with C and learning about the Standard Library—the Terminal application. Terminal is found in /Applications/ Utilities. In the Finder, you can use the shortcut to bring up the Utilities folder. Once there, double-click the Terminal application to launch it. You should see something similar to Figure 4-4. Don't worry if your Terminal window looks a bit different than mine. That's perfectly normal.
Figure 4-4. The Terminal window, as it appears when the application is first launched. Your Terminal window may look slightly different—no worries if it does.
