Latex 打印单斜杠、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] == '
' || tmp[0] == '
') {tmp++;}

当我将它包装在这样的 verb 命令中时:

When I wrap it in a verb command like this:

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

它不起作用，我得到:

! Undefined control sequence.

所有其他谷歌答案都如此复杂.

All other google answers are so complicated.

当然，必须有一个简单的方法来做到这一点，对吧?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反例:

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 ackslash，因此对于您的代码:

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

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

我忘了你在数学模式下需要这个命令.如果您希望一切都原样"，这就是您需要的代码(对于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] == `$ackslash$r' $|$ tmp[0] == `$ackslash$n') ${$tmp++;$}$
