Answer 1

Here the code provided is used as an example:

\documentclass{article}
\usepackage{fancyhdr}
\usepackage{lipsum}

\begin{document}
    % clear fancy header and footer
    \fancyhf{}

    % code start
    \fancyhead[LE]{\leftmark} 
    \fancyhead[RO]{\rightmark} 
    \fancyhead[CE,CO]{\thepage}
    \renewcommand{\headrulewidth}{0.4pt} 
    \renewcommand{\footrulewidth}{0pt}
    % code end

    % set pagestyle to use fancy header and footer
    \pagestyle{fancy}

    % insert some text into the document
    \markboth{lipsum 1}{demo 1}
    \lipsum[1-3]

    \markboth{lipsum 2}{demo 2}
    \lipsum[4-5]

    \markboth{lipsum 3}{demo 3}
    \lipsum[6-8]

    \markboth{lipsum 4}{demo 4}
    \lipsum[9-10]
