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 trouble compiling the program. It keeps giving me an error in my IntArray.cpp file, specifically in my base class's constructor where I call and initialize the superclass's constructor with the parameter of the base class's constructor. I'm not sure how to call a superclass's template constructor from a subclass's template constructor. The error message is shown below. Also, below the error message are my source code files for main.cpp, Array.cpp, Array.h, IntArray.cpp, IntArray.h, and Makefile. The program is not yet complete. I currently only have one method that gets the size of the array.
Error message from terminal:
IntArray.cpp:4:56: error: member initializer 'Array' does not name a non-static
data member or base class
