      My guess is that ChatGPT is just getting it wrong. Here are some of the other errors it gave when I had it retry:

      ref.cpp: In function ‘int main()’:
ref.cpp:6:12: error: invalid initialization of non-const reference of type ‘int&’ from an rvalue of type ‘int’
  int& i = k;
            ^
ref.cpp:10:12: error: invalid conversion from ‘int’ to ‘int&’ [-fpermissive]
  if (i == 17) {
            ^

      and

      ref.c: In function ‘int main()’:
ref.c:7:11: error: ‘int& i’ declared as reference but not initialized
  int& i = k;
           ^

      and

      ref.c: In function ‘int main()’:
ref.c:7:10: error: ISO C++ prohibits declaration of ‘k’ with no type [-fpermissive]
  int k = 17;
          ^
ref.c:7:10: error: ISO C++ prohibits declaration of ‘i’ with no type [-fpermissive]
ref.c:7:14: error: ISO C++ prohibits declaration of ‘i’ with no type [-fpermissive]

      I know that last one has to be wrong, int k = 17; is perfectly fine and has a type unlike what the error said.

      Weirdly I can't find where I tried to compile it with gcc and it said I needed to use g++.

        The original code is c++, so g++ was the right call. The first couple errors are c++ like, as & isn't part of the type system in C. But it's valid c++. This is the correct error in C, for some new-ish version of gcc:

        main.c: In function ‘main’:
main.c:7:8: error: expected identifier or ‘(’ before ‘&’ token
     int& i = k;^
main.c:9:5: error: ‘i’ undeclared (first use in this function)
 if (i == 17)

        This one is really interesting as it's the most basic bitch variable declaration, but it might get confused because int k probably isn't in the training lexicon.

        ref.c: In function ‘int main()’:
ref.c:7:10: error: ISO C++ prohibits declaration of ‘k’ with no type [-fpermissive]
  int k = 17;
