return type of conversion opeator

[George2]

Hello everyone,


In a class T, if there is a conversion opeator G, we always define it
like this,

operator G()

without return type. So the implicit return type is G or G&? I can not
find it in the C++ programming language book.


thanks in advance,
George

operator G&() is different from operator G().

The result type of operator T() is T according to §12.3.2/1.

G, you can however write an operator G&() if you want a reference.
