Discrete Structures: Overview: Lecture Notes | CISC 2210

Hello $\LaTeX$!

In the source code on the previous slide:

The command:
```
\documentclass{article}
```
defines the document type, which is an article in this case (can also be
```
book
```
,
```
report
```
, etc.).
- Above,
```
article
```
  is a required argument to the command
```
\documentclass{}
```
  .
- Some commands accept no arguments at all (like
```
\LaTeX
```
  ), while others may also accept optional arguments, too. Example:
```
\documentclass[12pt]{article}
```
  will set the font size of the entire document to $12$ points.
You can create a comment by putting a
```
%
```
(percentage sign) before it.
- A comment can also start in the middle of a line:
```
\documentclass[12pt]{article} % An article with a font size of 12 points.
```
The pair of commands:
```
\begin{}
```
and
```
\end{}
```
are called an environment, which is type of scope in your code. Specifically,
```
\begin{document}
```
and
```
\end{document}
```
define the document scope: everything between these two will be output to the PDF document.
