\begin{abstract}
This paper is a short example for the IEEEtran template. It introduces the most basic principles of latex and the paper format.

\section{Introduction}%
\label{sec:intro}

For scientific writing it is important to know how to cite related work~\cite{exampleThesis,exampleArticle,exampleBook}.
The bibliography at the end will be auto-generated.

\section{Example Code Listing}

As can be seen in \Cref{lst:example}, we have an example here. It will print \verb+"Hello"+ several times.
However, this example is not usable with ROP. For an example with figures, we refer the interested reader to \Cref{sec:figstabs}. We can also use the lame way of referencing another section, as can be evidenced in sections \ref{sec:figstabs} and \ref{sec:intro}.

\blindsection

\begin{figure}[b]
  % make figure go to bottom, others are: htbp (here, top, bottom, page). Most of time the default (top) fits best.
\begin{lstlisting}[language=C,firstnumber=17]
int main(int argc, char* argv[],
         char* env[])
{
  for (size_t i = 0; i < 10; i++) {
    // prints Hello some times
    printf("Hello %d\n", i);
  }
}
\end{lstlisting}

\section{Examples for figures and tables}%
\label{sec:figstabs}

\label{fig:latex}
\end{figure}

You can define the figure anywhere in the section and \LaTeX~(see \Cref{fig:latex}) will make it float to a place nearby.
You also can use the starred-version (\lstinline[language={[latex]tex}]+\begin{figure*}...\end{figure*}+) to define a figure that spans multiple columns. This was used for \Cref{tab:large-table}

\begin{table*}
