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).
