 ##### Example
 
-    enum class Webcolor { red = 0xFF0000, green = 0x00FF00, blue = 0x0000FF };
+    enum class Web_color { red = 0xFF0000, green = 0x00FF00, blue = 0x0000FF };
 
 
 ##### Note
 
 Switching on an enumeration is common and the compiler can warn against unusual patterns of case labels. For example:
 
-    enum class Productinfo { red = 0, purple = 1, blue = 2 };
+    enum class Product_info { red = 0, purple = 1, blue = 2 };
