<pre>Dies ist ein String!
Man kann einfache oder doppelte Anführungszeichen verwenden.
Innerhalb der Anführungszeichen kann man den jeweils "anderen Typ" verwenden
Oder 'andersherum'.
Alternativ kann man eine Backslash 'als' "Escape"-Zeichen verwenden
String-Literale, die direkt hintereinander, durch Leerzeichen getrennt, stehenwerden zusammengefügt.
Mit Klammerung klappt das auch über mehrere Zeilen hinweg
