Backslashes aren't escaped properly in Latex output

[nahumj]

Backslash characters (\\ in QBL) should become \textbackslash in Latex.

QBL content:

Both `std::cout << '\\n';` and `std::cout << std::endl;` cause a newline character to be 
emitted to standard output. Why is different about using `std::endl` to do so?

[*] It will also flush the stream's buffer
* It will also emit an EOF (`\\0`) character
* There isn't a difference
* `std::endl` requires non-whitespace characters to precede it 
* It will raise an exception if the stream is closed 

Wrong Latex Output generated by QBL:

Correct Latex Output:

\question Both \texttt{std::cout $<$$<$ '\textbackslash n';} and \texttt{std::cout $<$$<$ std::endl;} cause a newline character to be \\
emitted to standard output. Why is different about using \texttt{std::endl} to do so?
