As I'm only seeing C++ code ...

According to the "ISO 14882 - C++ 98" standards document NULL is a
MACRO and may be define in any of these standard includes -

<clocal>, <cstddef>, <cstdio>, <cstdlib>, <cstring>, <ctime>
or <wchar>

None of which you seem to have included within the code of these
screen captures.

Also the last error is because you have spelled "nodePtr" wrong. Don't know if you noticed this.

I usually use nil

Does nil work in C++? I thought that was an objective-c thing.

Oops, I believe you are correct.
