\lstinputlisting[language=C, title={変更元のソースコード}]{../programs/printf-formats/main.c}

上記のソースコードについて、\texttt{printf}関数と\texttt{scanf}関数の書式を次のように変更していく：

\begin{itemize}
    \item 第一の\texttt{printf}関数の書式を\texttt{\%f}にする
    \item 第一の\texttt{printf}関数の書式を\texttt{\%lf}にする
    \item 第二の\texttt{printf}関数の書式を\texttt{\%d}にする
    \item 第二の\texttt{printf}関数の書式を\texttt{\%lf}にする
    \item 第一の\texttt{scanf}関数の書式を\texttt{\%f}にする
    \item 第一の\texttt{scanf}関数の書式を\texttt{\%lf}にする
    \item 第二の\texttt{scanf}関数の書式を\texttt{\%d}にする
    \item 第二の\texttt{scanf}関数の書式を\texttt{\%f}にする
\end{itemize}
