RegexdrillEscaping: a price like $4.99
A regex exercise from Regexdrill. Solve it with a pattern box with live highlighting in your browser, checked against hidden test strings, and it is checked the moment you submit.
The task
The whole line must match. Match a dollar sign, one or more digits, a period and exactly two digits.
What this exercise teaches
\$ matches a real dollar sign and \. a real period. Without the backslashes, $ means end of line and . means any character.
A hint if you get stuck
$ and . have special meanings. Put a backslash in front of a special character to match it literally.
