In order to denote the byte with numerical value 1, followed by the digit 1, one could use "\1""1", since C concatenates adjacent string literals. Some three-digit octal escape sequences are too large to fit in a single byte. This results in an implementation-defined value for the resulting byte.
But it comes with a performance penalty for string literals, as std::string usually allocates memory dynamically, and must copy the C-style string literal to it at run time. Before C++11, there was no literal for C++ strings (C++11 allows "this is a C++ string"s with the s at the end of the literal), so the normal constructor syntax was used ...
FINDSTR flags strings [drive:][path]filename[...] Arguments: flags This can be any combination of flags described below. strings Text to be searched for. [drive:][path]filename Specifies a file or files to search. Flags: /B Matches pattern if at the beginning of a line. /E Matches pattern if at the end of a line. /L Uses search strings literally.
A string literal can contain the zero code unit (one way is to put \0 into the source), but this will cause the string to end at that point. The rest of the literal will be placed in memory (with another zero code unit added to the end) but it is impossible to know those code units were translated from the string literal, therefore such source ...

Most modern libraries replace C strings with a structure containing a 32-bit or larger length value (far more than were ever considered for length-prefixed strings), and often add another pointer, a reference count, and even a NUL to speed up conversion back to a C string. Memory is far larger now, such that if the addition of 3 (or 16, or more ...
Since UNCs start with two backslashes, and the backslash is also used for string escaping and in regular expressions, this can result in extreme cases of leaning toothpick syndrome: an escaped string for a regular expression matching a UNC begins with 8 backslashes – \\\\\ – because the string and regular expression both require escaping.
