Question

Is there a way in C++ to quote a string without having to escape with backslashes? For example, I would like a way to store some Latex code in a string, such as \documentclass{article}. I could do

string latex_code = "\\documentclass{article}"

But that gets annoying when you have to escape a lot of things, for example if you have a lot of Latex code. In Perl, I remember that you have some very useful quoting tools. See, for example, the “q” and “qq” sections here:

Is there something similar in C++? The only other thing I can think of is to paste the Latex code into an external file and read it in. But that also seems annoying.

C++11 has a way:

R"(The String Data \ Stuff " )"
R"delimiter(The String Data \ Stuff " )delimiter"

In the first case, everything between the “( and the )” is part of the string. The ” and \ characters do not need to be escaped. In the second case, the “delimiter( starts the string, and it only ends when )delimiter” is reached. The string delimiter can be any string up to 16 characters in length, including the empty string. This string cannot contain spaces, control characters, ‘(‘, ‘)’, or the ‘\’ character. The use of this delimiter string allows the user to have “)” characters within raw string literals. For example, R”delimiter((a-z))delimiter” is equivalent to “(a-z)”

It’s not possible in C++03.
