乳胶印刷单斜杠，反斜杠r，反斜杠n [英] Latex printing single slash, backslash r, backslash n

问题描述

我希望* .tex文件中的以下行按原样"打印:

I want the following line inside a *.tex file to be printed "as is":

while (tmp[0] == '\r' || tmp[0] == '\n') {tmp++;}

当我将其包装在\ verb命令中时，如下所示:

When I wrap it in a \verb command like this:

\verb"while (tmp[0] == '\r' || tmp[0] == '\n') {tmp++;}"

它不起作用，我得到:

! Undefined control sequence.

所有其他Google答案都很复杂.

All other google answers are so complicated.

当然，必须有一种简单的方法，对吗? 谢谢！

Surely, there's got to be an easy way to do this, right? Thanks!

这是评论中要求的最小计数器示例:

Here is the minimal counter example requested in the comments:

推荐答案

要在LaTeX中打印实际的反斜杠，请使用命令\backslash，因此对于您的代码:

To print an actual backslash in LaTeX you use the command \backslash, so for your code:

while (tmp[0] == '\backslash r' || tmp[0] == '\backslash n') {tmp++;}

编辑:我忘了您在数学模式下需要此命令.如果您希望一切都保持原样，这就是您需要的代码(垂直线和大括号也是如此):

I forgot you need this command in math mode. If you want everything "as is", this is the code you need (for the vertical lines and the curly brackets as well):

while (tmp[0] == `$\backslash$r' $\|$ tmp[0] == `$\backslash$n') $\{$tmp++;$\}$
