with carriage-return ("\r") you can jump back to the beginning of the current line. This will only work for terminals which have support for this feature.
有了carriage-return(“\r”)，您可以跳到当前行的开头。这只适用于支持此特性的终端。
After you jumped back you can just print your new status-line.
在您跳回去之后，您可以打印您的新状态线。

If you need to go back further than the last line and are using native Win API, you can use the SetConsoleCursorPosition method in kernel32.lib.
如果您需要回到上一行，并使用本机Win API，您可以在kernel32.lib中使用setcomfort ecursorposition方法。
Edit: GnuWin32 also seems to have a ncurses port if you can live with the dependencies on GnuWin32.
编辑:如果您可以使用GnuWin32上的依赖项，GnuWin32似乎也有一个ncurses端口。
