Question

In a template-declaration, explicit specialization, or explicit instantiation the init-declarator-list in the declaration shall contain at most one declarator. When such a declaration is used to declare a class template,no declarator is permitted.

Any one explain this ?

For me it is necessary that i need to check the compilers is following the ISO standard?
It is our project please help me?

Answer 1

That means you cannot write

template <class T> class A{} a, b;

or similarly

template <class T> A<T>::a=0, A<T>::b=1;

(imagine what would a, b be in the first case). For a more thorough explanation of declarators, see chapter 8 of the standard.
