Listings package not working properly with Exam class

Question

When I gave my code in the exam class like

\begin{parts}
\part \begin{lstlisting} 
echo The date is $date 
\end{lstlisting}
\part \begin{lstlisting} 
echo The date is $(date) 
\end{lstlisting}
\end{parts}

I want is the line starting with echo in (a) and (b) respectively. Instead that only \part displays only (a)

Answer 1

Putting it in \lstinline solved my problem

\begin{parts}
\part \lstinline{echo The date is $date}
\part \lstinline{echo The date is $(date)}
\end{parts}
