How to call a template super class's constructor from a template base class's constructor in c++?

Question

I\'m programming in c++ using sublimetext3. My program has a superclass called Array, and a subclass called IntArray. Both classes are template classes. Currently, I\'m having t

Answer 1

Use

template <class T> IntArray<T>::IntArray(T s) throw() : Array<T>(s) {}
                                                        //   ^^^ Use <T>

More importantly, put the implemetation also in the .h file.

See Why can templates only be implemented in the header file?.

Other Issues I Noticed

• It does not make sense that you are using T s for size. std::size_t s makes more sense.

• It does not make sense that IntArray is a class template. It makes more sense to me to use:

  class IntArray : public Array<int> { ... };
