C++: Is there a standard definition for end-of-line in a multi-line string constant?

Question

If I have a multi-line string C++11 string constant such as

R\"\"\"line 1
line 2
line3\"\"\"

Is it defined what character(s) the line termi

Answer 1

The standard seems to indicate that:

R"""line 1
line 2
line3"""

is equivalent to:

"line 1\nline 2\nline3"

From 2.14.5 String literals of the C++11 standard:

4 [ Note: A source-file new-line in a raw string literal results in a new-line in the resulting execution string literal. Assuming no whitespace at the beginning of lines in the following example, the assert will succeed:

const char *p = R"(a\
b
c)";
assert(std::strcmp(p, "a\\\nb\nc") == 0);

—end note ]

5 [ Example: The raw string

R"a(
)\
a"
)a"

is equivalent to "\n)\\\na\"\n".
