Kinda neat but it looks extremely limited in ways that I think would frustrate a beginner:

E.g. the following doesn't do anything

  #include <iostream>
  using namespace std;
  int get7() { return 7; }
  int main() { return get7(); }

but if you manually inline the get7() it displays 7, so returning the value from another function doesn't work which seems quite odd and I think would preclude playing with recursion. (You can assign the get7() return value to a local var and return that and it works so there is a workaround but it's awkward.)

Similarly, if there are compiler errors it gives no indication as to what the error might be. C++ compiler errors are always pretty terrible but not showing anything about where even a parse went wrong could really get in the way of fixing typos etc that can really get in the way of learning the concepts.

In this case there are no variables updated so the editor is not very useful indeed. The parsing erros for this interpreter are very limited, however there is internal access to the location of the failure (line, column) so there could be added a red underline to suggest the errors. Thanks for the feedback!
