Basic paragraphs and comments

Creating paragraphs and new lines

In very important documents, such as scientific ones, you do not want to keep a simple, basic format. In Latex, for example, if you want to start a new paragraph, you have to click the "Enter" key twice, and if you write on a new line and not start a new paragraph, you can write a backslash two times (\\), after the line previous to the new line. For example:

CODE


                                        \documentclass{article}
                                        

                                        

                                          \title{My first Latex Document!}
                                          

                                          \author{Bob Malcom}
                                          

                                          \date{November 2, 2018}
                                          

                                          

                                          \begin{document}
                                          

                                          

                                          \maketitle
                                          

                                          

                                          Hello World! This is a very simple, Latex document. \\
                                          

                                          

                                          This is a new line \\
                                          

                                          

                                          This is another line.
                                          

                                          

                                          This is a new paragraph.

Comments

We saw from the code and the picture of the document, that a new line goes simply down a line, while a paragraph does the same, but gets indented.

On Latex, it is also possible to insert comments (colored in red), useful for remembering what you meant in one of your lines of code. Very simply, you type the symbol "%", and start writing the comment. When you are finished with the comment, you press the "Enter" key. Below, for example:

CODE


                                        \documentclass{article}
                                        

                                        

                                      \title{My first Latex Document!}
                                      

                                      \author{Bob Malcom}
                                      

                                      \date{November 2, 2018}
                                      

                                      

                                      \begin{document}
                                      

                                      

                                      \maketitle %Title inserted
                                      

                                      

                                      Hello World! This is a very simple
                                      Latex document. \\ %This is a text, containing the command that lets the following text go down the next line.
                                      

                                      

                                      This is a new line \\ %This is a text, containing the command
                                        that lets the following text go down the next line
                                        

                                        

                                      This is another new line. %This is a text, containing the command
                                        that creates a new paragraph (double "Enter" key)
                                      

                                      

                                      This is a new paragraph. %Final text (in new paragraph)
                                      

                                      

                                      \end{document}

As you may imagine, comments will not appear on the actual Latex document, so the document for the code above will be the same as the first picture at the top of this page. This is a very useful tool, because it makes the coder remember what he/she meant with a particular code, or line of code. Are you not so sure about remembering in the future what you have written, or what your code really means? Put a % and write your comment!
