+## 2.3 Repetitions
-We can repeat a character class by using `+`, `*` or `?` operators. For example the regular expression `[a-z]+` means: any number of
-lowercase letters in a row.
+Following meta characters `+`, `*` or `?` are used to specify how many times a subpattern can occurs. These meta characters act
+differently in different situations.
+
+### 2.3.1 The Star
+
+The symbol `*` matches zero or more repetitions of the preceding matcher. The regular expression `a*` means: zero or more repetitions
+of preceding lowercase character `a`. But if it apperas after a character set or class that it finds the repetitions of the whole
+character set. For example the regular expression `[a-z]*` means: any number of lowercase letters in a row.
-"[a-z]+" => The car parked in the garage.

+The `*` symbol can be used with the meta character `.` to match any string of characters `.*`. The `*` symbol can be used with the
+whitespace character `\s` to match a string of whitespace characters. For example the expression `\s*cat\s*` means: zero or more
+spaces, followed by lowercase character `c`, followed by lowercase character `a`, followed by lowercase character `t`, followed by
+zero or more spaces.

+"c.+t" => The fat cat sat on the mat.

+### 2.3.3 The Question Mark

+In regular expression the meta character `?` makes the preceding character optional. This symbol matches zero or more repetitions of
+the preceding character. For example the regular expression `[T]?he` means: Optional the uppercase letter `T`, followed by the lowercase
+character `h`, followed by the lowercase character `e`.
