来自题库的编号试卷

我已经看到了一种方法从题库生成考试吗？ 从题库生成试卷。我有一个问题：我们如何枚举（我需要连续的问题编号）问题？

答案1

如果目的仅仅是让一个计数器在每次打印新问题时递增，我们可以添加一个新的计数器\newcounter{numberedquestions}，并在每次打印问题时打印并递增该计数器，方法是将以下内容替换为沃纳的回答到从题库生成考试吗？

\ifnum\value{questionblock}=\randomquestion 
  \par% Start new paragraph
  \BODY% Print question
\fi

和

\ifnum\value{questionblock}=\randomquestion 
  \par% Start new paragraph
  \stepcounter{numberedquestions}
  \arabic{numberedquestions}. \BODY% Print question
\fi

每次打印一个问题（\BODY）时，问题都会以 为前缀\arabic{numberedquestions}.（或任何需要编号的格式）来给出问题编号，并且计数器会增加以跟踪打印的问题数量。

将上述内容更改为沃纳的回答我们有
