The Enter key always send a single CR '\r'. If you are in cooked mode, this '\r' is replaced by the driver to a LF '\n' a.k.a newline.

When outputting characters in cooked mode, '\n' is replaced by CR+LF '\r\n'.

When you are in raw mode, characters are left unchanged.

The best way is to just avoid using getchar on the standard input and use scanf and sscanf to parse input. Then again scanf brings the possibility of buffer overflows into the mix.
