[Tex/LaTex] Change the subsection numbering style

Question

I'm writing an article in LaTeX, and, as always the content numbering style is like this:

1 section title

1.1 subsection title

1.2 subsection title

2 section title

...

I want to know if it's possible to obtain something like this:

1 section title

A subsection title

B subsection title

2 section title

...

Answer 1

Assuming you're using one of the default LaTeX document classes -- article, report, and book -- you could try

\renewcommand\thesubsection{\Alph{subsection}}

A full MWE (minimum working example):

\documentclass{article}
\renewcommand\thesubsection{\Alph{subsection}}
\begin{document}
\section{First section}
\subsection{First subsection}
\subsection{Second subsection}
\section{Second section}
\subsection{Another subsection}
\end{document}
