Raw Strings

For more easily specifying strings that have lots of special characters (think newlines and backslashes) such as regular expressions or parser grammars.

The basic syntax is:

R"(some complex string)"

Since in some situations the sequence )" might occur in the string, additional characters can be between the R and the ", e.g.:

R---"(some complex string)---"
