Dear All,

Such as I have a template class Base<intwhich can automaticaaly
convert to base<douoble>.

Base<int <= Base<double>

And also I have a derived class Derived<intwhich can automatically
convert to Derived<double>.

Derived<int<= Derived<double>

And I have a function

void fun(Base<int>)

If I call

Derived <doublea;
fun(a);

It is ambiguous in the type conversion. Is there any good way I can
avoid it?

Thanks,

Tian

What do you mean by "to avoid"? Which one do you actually need? Or
do you want an error message instead?

Got your message, Thanks.
I am wondering what is capital 'A's?

Those are letters 'A' (compared to letters 'a', which are called "small",
if memory serves me).
