NOTE: This is being written in the .cpp of Class3



both ds[] and org[] are in the header file of Class3 so I keep getting the "was not declared in this scope"...
In order to fix this, I'd have to do Class3::getSequence(Class2 organism), but I HAVE to keep it as Class1 getSequence(Class2 organism)
Is there any way to make this work?

I wanted to do this:



But here it says "invalid use of non-static data member 'Class3::ds', so what can I do here?

Sounds like you're getting some concepts mixed up here.

The method signature

means that your method will return an object instance of type Class1.

The call

is a method inside the class, Class3, which presumably returns *something* (you haven't actually told us what it is here.. but I'm going to assume that it needs to return an object of type Class1, as you noted above).

Last but not least, non-static data/methods are meant to be called from a specific instance of a class. In this case, you're trying to access the array ds[] statically, when it's not a static data variable.

Anyway, with this and with scoping problems in general, you're going to need to post *all* the relevant before people can help you. In most cases, just a snippet will not tell anybody anything.

Well I found a solution, but have another problem. I'll make another thread since this is irrelevant now
