The . Character
The next special character we will consider is the . character. The
. will match any valid character. As an example, consider the
regular expression a.c. This regular expression will match any
string that contains an a and a c, with any possible character
in between. Thus, strings that contain abc, acc, amc,
etc. are all in the class of strings that this regular expression
matches.
