Hi all,
We some time need to use \subsubsection when writing reports/books in latex. Although this kind of use is rare its still sometimes required. By default subsubsection will not be numbered in book or report class.
To use add :
\setcounter{secnumdepth}{3}
to the preamble, and you will see the subsubsection is now being numbered. Basically the above line instructs latex to use 3 level of numbering instead of default 2 (chapter -> section -> subsection).
Thanx for reading:)
