如何在控制台项目中重写一行文本?C ++ [英] How do I rewrite a line of text in a console project? c++

问题描述

我正在研究c ++控制台项目，我想显示一个百分比而不每次都换行(以免窗口被成千上万的行阻塞).

I'm working on a c++ console project and i would like to show a percentage without making a new line each time (so that the window doesn't get clogged with thousands of lines).

是否可以删除最后打印的一行，或者说我下次输出一行时应该替换当前行?

Is there a way of removing the last line that was printed or something to say that the next time that i output a line it should replace the current line?

推荐答案

您可以使用\ r(回车)将光标返回到行首:

You can use a \r (carriage return) to return the cursor to the beginning of the line:

这适用于Windows和Linux.

This works on windows and Linux.

来自:您也可以使用一系列的退格键.

You could alternatively use a series of backspaces.

string str="Hello!";
cout << str;
cout << string(str.length(),'\b');
cout << "Hello again!";
