I''d like printf, the next printf, to return to the start of the line just
printed. In other words, I want to keep print over the same portion of the
screen again and again. 01, 02, 03, ... Is there some /X that does that?

printf（如何不被看见）;
printf（\rMove上，没有什么可看的）;
也可能对你有用：''\ b' '

电子邮件：我的是/ at / gmx / dot / de address。
printf("How not to be seen");
printf("\rMove on, there is nothing to be seen");
Also potentially useful for you: ''\b''
Cheers
