+ +

+C++ changes to ENUM. +

+ + +

+ +

In the C++ world, the rules applying to +enum have been altered. + +

Definitions no longer require the enum prefix or a +typedef fudge. +

+ + + + +

+
+    main ()
+    {
+        enum Currancy = {STERLING, DOLLAR, RUPEE};
+                                                                
+        enum Currancy GreenBack = DOLLAR;     // Valid in C and C++
+        Currancy Pounds = STERLING;           // Valid in C++ only.
+
+    }
+

+ + + +

+An enum is no longer considered to be an int +datatype. Because it has its own datatype you can not perform normal arithmatic +apon enum variables. The following program is now invalid.

+ + + + +

+
+    main ()
+    {
+        enum Currancy = {STERLING, DOLLAR, RUPEE};
+
+        Currancy Pounds = STERLING;
+
+        Pounds = 2;             // Invalid Statement.
+
+        Pounds++;               // Invalid Statement.
+    }
+
