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}
