How can I add the word "Chap" before the chapters numbers in the Toc in class report?

Question

At here Adding the word "Chap" before the chapters numbers in the TOC the word Chapter added in \documentclass{book}. Now I want to use them in \documentclass{report}. How can I do that?

I don't understand the error. Can you please mention the code? right now in my thesis, \section are used for every chapter which displays chapter like 1 introduction, 2 literature. I'm using this \documentclass[12pt, chapterprefix]{article} \usepackage[a4paper, margin=20mm]{geometry}? — Sajed ahmad, Mar 13 '24 at 04:44

Here's the modification for the report class (basically, it's the same code but suppressing the conditional test for the \frontmatter); I defined two commands \AddChap and \SuppChap to activate (deactivate, resp.) the addition:

\documentclass{report}

\makeatletter
\let\orig@chapter\@chapter
\newcommand\SuppChap{%
  \let\@chapter\orig@chapter}
\newcommand\AddChap{%
\def\@chapter[##1]##2{\ifnum \c@secnumdepth >\m@ne
                         \refstepcounter{chapter}%
                         \typeout{\@chapapp\space\thechapter.}%
                         \addcontentsline{toc}{chapter}%
                                   {Chap~\protect\numberline{\thechapter}##1}%
                       \else
                         \addcontentsline{toc}{chapter}{##1}%
                       \fi
                    \chaptermark{##1}%
                    \addtocontents{lof}{\protect\addvspace{10\p@}}%
                    \addtocontents{lot}{\protect\addvspace{10\p@}}%
                    \if@twocolumn
                      \@topnewpage[\@makechapterhead{##2}]%
                    \else
                      \@makechapterhead{##2}%
                      \@afterheading
                    \fi}%
}
\makeatother

\begin{document}

\tableofcontents

\chapter{Acknowledgements}

\AddChap
\chapter{Test Chapter One}
\chapter{Test Chapter Two}

\SuppChap
\appendix
\chapter{Test Appendix One}

\end{document}

A much simpler solution with the tocloft package.

\documentclass{report}
\usepackage{tocloft}

\newlength\mylength

\renewcommand\cftchappresnum{Chap~}
\settowidth\mylength{\bfseries\cftchappresnum\cftchapaftersnum}
\addtolength\cftchapnumwidth{\mylength}

\begin{document}

\tableofcontents

\chapter{Intro}

\chapter{Test}

\end{document}

Output (ToC):

EDIT

If you want to add the word "Appendix" instead of "Chap" for your appendices, you can load the package etoolbox and add the following lines in your preamble:

\apptocmd{\appendix}
  {\addtocontents{toc}{%  
   \protect\addtolength\protect\cftchapnumwidth{-\mylength}%
   \protect\renewcommand{\protect\cftchappresnum}{Appendix~}%
   \protect\settowidth\mylength{\bfseries\protect\cftchappresnum\protect\cftchapaftersnum}%
   \protect\addtolength\protect\cftchapnumwidth{\mylength}}%
  }{}{}

Complete MWE:

\documentclass{report}
\usepackage{tocloft}
\usepackage{etoolbox}
\apptocmd{\appendix}
  {\addtocontents{toc}{%  
   \protect\addtolength\protect\cftchapnumwidth{-\mylength}%
   \protect\renewcommand{\protect\cftchappresnum}{Appendix~}%
   \protect\settowidth\mylength{\bfseries\protect\cftchappresnum\protect\cftchapaftersnum}%
   \protect\addtolength\protect\cftchapnumwidth{\mylength}}%
  }{}{}

\newlength\mylength

\renewcommand\cftchappresnum{Chap~}
\settowidth\mylength{\bfseries\cftchappresnum\cftchapaftersnum}
\addtolength\cftchapnumwidth{\mylength}

\begin{document}

\tableofcontents

\chapter{Intro}

\chapter{Test}

\appendix

\chapter{Conclusions}

\end{document}

Output (ToC):

@minthao_2011 Do you have something like \chapter*{appendix} in your document? – karlkoeller Feb 13 '14 at 05:13
No. I have some appendices. – minthao_2011 Feb 13 '14 at 05:14
@minthao_2011 Are you saying that you want to insert the word Appendix instead of Chap for your appendices? – karlkoeller Feb 13 '14 at 05:21

@ karlkoeller How can I add the dot (.) after the Chap in Toc? – minthao_2011 Oct 30 '14 at 15:20
@minthao_2011 Sorry for the late reply. Simply change the definition to \renewcommand\cftchappresnum{Chap.~} if you want the dot before the number or add \renewcommand\cftchapaftersnum{.} if you want it after the number. – karlkoeller Jun 28 '15 at 14:43
