Answer 1

您的代码中有几个错误。我<==========在以下 MWE 中更正了它们（用 标记了重要更改）。要使用命令，\includegraphics您必须加载/调用包graphicx。我还更正了一些 typhos。

以下 MWE

\documentclass[10pt]{article}

\usepackage{graphicx} % <===============================================

\author{soham}


\begin{document}

\title{First Document}
\maketitle
This is my first document \& I like editing in LaTeX \cite{ab}. % <=====
\begin{enumerate}
\item Hello % <=========================================================
\end{enumerate}
\begin{figure}
\includegraphics[scale=0.5]{example-image} % <==========================
\end{figure}
\begin{thebibliography}{9}
\bibitem {ab}
Holland, J.H., Adaptation in Natural and Artificial Systems. University of Michigan Press, 1975.
\end{thebibliography}
