Troubleshooting LaTeX Error: 'There's no line here to end'

The error message 'There's no line here to end' typically occurs in LaTeX when a figure environment is not followed by any text, leaving it hanging without belonging to a paragraph. Here's how to fix it:

Instead of this:

\begin{figure}[H]
  \centering
  \includegraphics[scale=0.5]{Figure/addatt}
\end{figure}

Do this:

\begin{figure}[H]
  \centering
  \includegraphics[scale=0.5]{Figure/addatt}
  \caption{Your figure caption}
  \label{fig:your_figure_label}
\end{figure}

Here is the explanation for Figure \ref{fig:your_figure_label}. Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nullam ut semper justo. Integer eu urna vitae nunc vehicula ultricies vitae vitae ipsum.

Explanation:

• Add Text After the Figure: The key is to ensure the figure environment is part of a paragraph. We achieve this by adding explanatory text after the figure code.
• Use Captions and Labels: Utilize \caption to provide a descriptive caption for your figure and \label to assign it a unique identifier for easy referencing within your document using \ref.
