Question
Which regular expression symbol represents one or more occurrences of a specific character?
- 分
- \w*
- \d+
Solution
The regular expression symbol that represents one or more occurrences of a specific character is the plus sign (+).
Here's a step-by-step explanation:
-
Regular expressions (regex) are sequences of characters that form a search pattern. They are used in programming to match, locate, and manage text.
-
In regex, different symbols represent different types of search patterns.
-
The plus sign (+) is a special symbol in regex. It means "one or more occurrences of the preceding element."
-
For example, if you have the regex pattern "a+", it will match "a", "aa", "aaa", and so on because these strings have one or more occurrences of the character "a".
-
So, if you want to represent one or more occurrences of a specific character in regex, you would use that character followed by a plus sign (+).
