All I want is a simple thing: Change the section numbering to become like this

1.  Introduction

And not the default, where there is no point. I also want to make the point appear for the subsection and the subsubsection.

  • Welcome to TeX.SX! Please help us help you and add a minimal working example (MWE) that illustrates your problem. Reproducing the problem and finding out what the issue is will be much easier when we see compilable code, starting with \documentclass{...} and ending with \end{document}. – samcarter_is_at_topanswers.xyz Jan 02 '16 at 20:00
  • Usually, we don't put a greeting or a “thank you” in our posts. While this might seem strange at first, it is not a sign of lack of politeness, but rather part of our trying to keep everything very concise. Accepting and upvoting answers is the preferred way here to say “thank you” to users who helped you. – samcarter_is_at_topanswers.xyz Jan 02 '16 at 20:01
  • I've found the solution on this link, if somebody is interested, please visite the link here: http://tex.stackexchange.com/questions/96692/changing-the-section-title do as it is mentionned, but just write this : \def@seccntformat#1{\csname the#1\endcsname.\quad} instead of what's written there. P.-S: i'm new to the formum, so i'll try to be more concise in the future, appreciate your help. – Zine Jan 02 '16 at 20:06
  • @zine Since it seems that you are just beginning with LaTeX you might be better off using the package based solution in my answer or in the linked duplicate question. – Alan Munn Jan 02 '16 at 20:13

The simplest way to change section headings in the standard document classes is with the titlesec package:

\usepackage{titlesec}
\titlelabel{\thetitle.\quad}

If you are using the KOMA classes, you can set this as a class option:

\documentclass[numbers=endperiod]{scratcl}
