Question

What is the syntax to use explicit class specialization?

(a) template <int> class myClass<>{  }

(b) template <int> class myClass<int>{  }

(c) template <> class myClass<>{  }

(d) template <> class myClass<int>{  }

The question was posed to me by my college director while I was bunking the class.

My query is from Template Class in portion Classes of Object Oriented Programming

Answer 1

Right choice is (d) template <> class myClass<int>{  }

Explanation: The class specialization is creation of explicit specialization of a generic class. We have to use template<> constructor for this to work. It works in the same way as with explicit function specialization.
