The slash is also used as the default regular expression delimiter, so to be used literally in the expression, it must be escaped with a backslash \, leading to frequent escaped slashes represented as \/. If doubled, as in URLs, this yields \/\/ for an escaped //.
For example, forward slash characters are used to separate different parts of a URL (or, more generally, a URI). Unreserved characters have no such meanings. Using percent-encoding, reserved characters are represented using special character sequences.
Strings are delimited with double quotation marks and support a backslash escaping syntax. Boolean: either of the values true or false; Array: an ordered list of zero or more elements, each of which may be of any type. Arrays use square bracket notation with comma-separated elements.
Modern and POSIX extended regexes use metacharacters more often than their literal meaning, so to avoid "backslash-osis" or leaning toothpick syndrome, they have a metacharacter escape to a literal mode; starting out, however, they instead have the four bracketing metacharacters ( ) and { } be primarily literal, and "escape" this usual meaning ...
The octal escape sequence ends when it either contains three octal digits, or the next character is not an octal digit. For example, \11 is an octal escape sequence denoting a byte with decimal value 9 (11 in octal). However, \1111 is the octal escape sequence \111 followed by the digit 1.
As Elon Musk goes line by line down the federal budget to slash, as he claims, trillions of dollars in waste, he's offering up sacrifices akin to what bad personal finance gurus target in an ...
ARM are expressed as two numbers separated by a slash — for example, a 5/1 ARM loan. In this case, the 5 represents the number of years your rate is locked with the 1 representing the frequency ...
In C and many derivative programming languages, a string escape sequence is a series of two or more characters, starting with a backslash \. [3]Note that in C a backslash immediately followed by a newline does not constitute an escape sequence, but splices physical source lines into logical ones in the second translation phase, whereas string escape sequences are converted in the fifth ...
