The backslash (\) escape character typically provides two ways to include double-quotes inside a string literal, either by modifying the meaning of the double-quote character embedded in the string (\" becomes "), or by modifying the meaning of a sequence of characters including the hexadecimal value of a double-quote character (\x22 becomes ").
An escape sequence starts with a backslash (\) called the escape character and subsequent characters define the meaning of the escape sequence. For example, \n denotes a newline character. The same or similar escape sequences are used in other, related languages such C++, C#, Java and PHP.
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 ...
Some software replaces the backslash+newline with a space. [10] To support computers that lacked the backslash character, the C trigraph??/ was added, which is equivalent to a backslash. Since this can escape the next character, which may itself be a ?, the primary modern use may be for code obfuscation.
Because certain characters cannot be part of a literal string expression directly, they are instead identified by an escape sequence starting with a backslash (\). For example, the backslashes in "This string contains \"double quotes\"."
The backslash is used to represent the escape character in a string literal. Many languages support the use of metacharacters inside string literals. Metacharacters have varying interpretations depending on the context and language, but are generally a kind of 'processing command' for representing printing or nonprinting characters.
This includes the escape character itself, the backslash (“\”), which is escaped by itself (“\\”). For every sublevel in which a backslash is contained, it must be escaped for the level above it, and then all the backslashes used to escape that backslash as well as the original backslash, must be escaped, and so on and so forth for ...
In computer programming, leaning toothpick syndrome (LTS) is the situation in which a quoted expression becomes unreadable because it contains a large number of escape characters, usually backslashes ("\"), to avoid delimiter collision. [1] [2]
