引用算法中的行号

Question

引用数字很简单：

\begin{figure}
    \caption{Blah blah blah blah blah}
    \label{fig:name}
    %shtuff goes here
\end{figure}

See figure~\ref{fig:name}.

我想知道是否可以在算法中引用行号，例如：

\begin{algorithmic}[1]
    \State blah1
    \State blah2 \label{lst:line:blah2}
    \State blah3
\end{algorithmic}

As you can see on line~\ref{lst:line:blah2} \ldots

Answer 1

当然可以；这是一个基于您的代码片段的简单示例：

\documentclass{article}
\usepackage{algpseudocode}

\begin{document}

\begin{algorithmic}[1]
    \State blah1
    \State blah2 \label{lst:line:blah2}
    \State blah3
\end{algorithmic}

As you can see on line~\ref{lst:line:blah2} \ldots

\end{document}
