std :: cout打印N次字符 [英] std::cout to print character N times

问题描述

如何使用 std :: cout 打印N次字符而不循环？

How can I print a character N number of times using std::cout without looping?

是有一种方法可以将文本光标移回以使 std :: cout<<的效果无效。 std :: endl; ？即向上移动（例如，在执行 std :: cout<< std :: endl; 操作之后，我们从不打印任何内容）。

Is there a way to move the text cursor back to nullify the effect of std::cout << std::endl;? i.e. to move up a line (say we never printed anything after doing the std::cout << std::endl; operation).

推荐答案

 std::cout << std::string(100, '*') << std::endl;

要向上移动一行，必须诉诸终端逃生（假设 isatty（）表示您正在运行一个。）

To move a line up, you have to resort to terminal escapes (assuming that isatty() indicates that you are running on one).
