- Hi,
-
- I have the following piece of code,
-
- void goo(int);
- void goo(unsigned int);
-
- enum Enum {E1,E2}
-
- void foo ()
- {
- Enum e = E1;
- goo(e); // Is this call ambiguos?
- }
-
- The DWP in 4.5 (integral promotion) point 2 says that
- "An rvalue of type wchar_t or an enumeration type can be converted to an
- rvalue of the _first_ of the following types that can represent all the values
- of the source type: int, unsigned int, long, unsigned long."
-
- Does this mean that in the above example the call to goo(e) should be resolved
- to goo(int)? or in other words is the promotion enum -> int better than
- enum -> unsigned int in this case?
-
- thanks in advance
