Since it happened in the first 5 lines, can we see at least the first 6 lines of code?

No one here is going to open up some random Word document in MS Word, where there could be random macro viruses in it.

Fortunately for you, I use LibreOffice instead, and the macros are all disabled. So, let me post the code for you as you were requested to do in the first place:

This brings us to the error messages:

• The headers are in the wrong format for modern C++, which leads me to think it was originally written for Turbo C++; however, TC++ didn't support use namespace, which is presumably why you get an error message on line 5.
• The header <graphics.h> is specific to TC++, and shouldn't be used any more. If you are using it because you are using TC++, stop and throw that ancient piece of garbage away, and start over with a modern C++ compiler.
• You have the function Line.bss() in the declaration of the class, meaning that it inlined by default. Inline functions, generally speaking, should only be used for very small pieces of code. For some reason, you compiler enforces this by not accepting do or while statements in inlined code.
• there is an extra trailing close brace at the end of the program.

[Schol-R-LEA]

You would move the method out of the class declaration, preferably moving the declaration, implementation, and main() into separate compilation units.

Note that this probably still won't work, as it uses the Turbo C++ specific library <graphics.h>, but this should at least get you on the right track.

And to repeat what I said earlier: DO NOT USE TURBO C++! It is so out of date as to be useless for present-day programming.

If you are in a class where the professor requires it, quit that class and complain to the university administration.
