 |
|
hi, all
Suppose I have a template class A
template<class T> class A{...}
Then I have another class B which inherits class A. Should I say
class B: public A{...}
or class B: template<class T> A{...}
or template<class T> class B : public A {...}
or something else? I assume that class A is also a template. But can
class A be a non template class? If yes, how can A handle the different
type of T? Thanks ahead.

template<class T>
class Derived : public Base<T> {
};

Depends.
If you want class B to be a template like class A, then:
template <class T>
class B : public A<T>
{
// ...
};
If you want that class B inherits from a specific class A, say with
template parameter int:
class B : public A<int>
{
// ...
};
