hyphen punctuation

1 Word count (10 points)Topic content:Your program reads an English article and then counts the number of words to output. The data to be counted are: The total number of words; The number of words that contain 1 letters to 10 letters. The spacing between words and words is formed by the following punctuation marks: spaces, tabs, carriage returns, commas, periods, question marks, parentheses, double quotes, and colons. These symbols

characters, not hyphens, more winners, or no separators at all, or 7 digits together. In these cases, we can use (-|)? To solve. The regular expression of this structure is the converter, which can match several of the above mentioned cases. When () can contain a pipe character |, it can match whether it contains a space character or a hyphen, and the tail of the "metacharacters" indicates whether there is no delimiter at all. Finally, the location n

a match is found, the sarh method returns an integer indicating the offset position starting from the string. If no match is found,-1 is returned. Example \\The following example demonstrates the use of the sarh method.Funtin Sarhm () {var r, r; // declare the variable. Var s = "Th rain in Spain falls mainly in th plain."; r =/falls/I; // create a regular expression pattern. R = s. sarh (r); // search for strings.

Mysql regular expressions I personally think that the regular expressions in other program scripts are not much different in usage and rules. Next I will summarize some of the mysql Regular Expressions and instance methods. "." Matches any single character. A character class "[...]" matches any character in square brackets. For example, "[abc]" matches "a", "B", or "c ". To name a range of characters, use a hyphen (-). "[A-z]" matches any lowercase le

what is a character cluster? In programs in the Internet, regular expressions are often used to validate the user's input. When the user submits a form, to determine whether the input phone number, address, email address, credit card number, etc. is valid, with ordinary literal-based characters is not enough. So to use a more liberal way of describing the pattern we want, it's a character cluster. To create a character cluster that represents all vowel characters, place all the vowels in a squ

that the pattern matches only those strings that begin with once. For example, the pattern matches the string "Once Upon a Time" and does not match "there once is a man from NewYork". Just as the ^ symbol represents the beginning, the $ symbol is used to match strings that end in a given pattern. bucket$ This pattern matches the "who kept all of the cash in a bucket" and does not match "buckets". The characters ^ and $ are used together to indicate exact matches (the string is the same as the

characters..(Point) matches any single character, except NULL.*Match any number of characters (can be 0 ). In the case of ERE, this prefix is a regular expression, as shown in figure.*Represents the length of matching any character. But for BRE,*Placed in the first character of the regular expression does not have any special meaning.^(Remove font size) matches an empty string at the beginning of the line or the start of the string.ERE: It has a special meaning in any position;BRE: It has this

only backslashes \ Hold special meanings for escaping characters. Other special Furus numbers, plus signs, and various parentheses are all common characters. The caret ^ if present in the first place indicates a negative character set, if it appears in the string only as ordinary characters. Hyphen-Indicates a character range description if it appears in a string, or only as a normal character if it appears in the first place.[^XYZ] Exclusion type (n
