C ++改变输出从“cout” [英] C++ Change Output From "cout"

问题描述

是否可以更改用cout打印的文本？我想让它显示当前百分比的东西，而不必为每个百分比的新行。这可能吗？

Is it possible to change text printed with "cout"? I would like to make it show the current percentage of something without having to have a new line for each percentage. Is this possible?

推荐答案

这适用于我：

std::cout << "1111";
std::cout << "\r";
std::cout << "2222";

\r 是回车符。

也可以使用 \b 字符。这是退格。当打印时，它返回一个字符。

Alternatively you can use \b character. This is backspace. When printed it goes one character back.
