[Tugindia] How to create Subchapters

[Harish Kumar Holla]

Here is some starter.

\documentclass{book}
\usepackage{titlesec}
\titleclass{\subchapter}{straight}[\chapter]
\newcounter{subchapter}
\renewcommand{\thesubchapter}{\Alph{subchapter}}

\newcommand{\subchaptertitlename}{Sub chapter}

\titleformat{\subchapter}[display]   %% adjust whether this should be
display or not
{\normalfont\LARGE\bfseries}{\subchaptertitlename\
\thechapter.\thesubchapter}{15pt}{\huge}

\titlespacing*{\subchapter} {0pt}{50pt}{40pt}  %% adjust this spacing
\begin{document}
  \chapter{Introduction}
  Some introductory text here.
  \subchapter{Some subchapter}
  Text here
  \section{Section here}
  \subchapter{Some subchapter}
  Text here
  \section{Section here}
  \subchapter{Some subchapter}
  Text here
  \section{Section here}

  \chapter{First chapter}
  Some introductory text here.
  \subchapter{Some subchapter}
  Text here
  \section{Section here}
  \subchapter{Some subchapter}
  Text here
  \section{Section here}
  \subchapter{Some subchapter}
  Text here
  \section{Section here}
\end{document}
