6.2.3 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.
