How to call constructor of a template base class in a template derived class?

Question

Let\'s say I have a base template class Array:

template  class Array{
    protected:
        T* m_data;
        int size;
    public:
             


        

Answer 1

Combine your solutions, use the initializer list and the full name:

NumericArray::NumericArray(int n)
 : Array(n)
{

}

Also, since they become a dependent name, fields of Array have to be accessed like this:

Array::m_data; // inside a NumericArray method

Also, if it's not some experiment or homework, please use std::vector instead of pointer and size.
