Templates are sections of code that occur frequently enough that you would like
to be able to insert them with a few keystrokes.
This function is known as Content Assist; the sections of code that are
inserted are known as templates.
To input an existing Content Assist template into a file, such as one for an
if statement, type the initial character ("i" in this case), then press Ctrl+Space.
The templates that begin with that character appear. Double-click on a template to insert it into a file.
You can edit existing Code/Content Assist templates or create new ones. From the menu bar choose
Window > Preferences > C/C++ > Editor > Templates.
