[Tex/LaTex] Printing LaTeX command without compiling it

Question

How could I write a command in LaTeX, so after compiling it will be shown as a text in PDF and not executed?

For Example, I would write \it This is how you write in italic and the compiled pdf would contain the exact same text between the quotation marks without \it being executed.

Answer 1

You can put them in the verbatim environment.

\begin{verbatim}
\it This is how you write in italic
\end{verbatim}

P.S. If you need to put them in-line, you can put them in the \verb== environment:

\verb=\it This is how you write in italic=
