Why can't I override the default copy constructor and assignment operator with template versions in C++

Question

I asked this question about overloading the copy constructor and assignment operator with template versions and considering the confusion involving around the question (sinc

Answer 1

template
BaseClass(const T& a_other) 

First of all, this is not a copy-constructor. It is rather a templated constructor.

The copy-constructor should be this:

BaseClass(const BaseClass & a_other)

Notice the difference?

Note that the templated constructor doesn't define copy-constructor. The compiler will still generate a default copy-constructor for you, instead of instantiating the templated constructor.

Same argument for copy-assignment.
