c++ - Print on the screen the symbol \ as text -

-

this question has answer here:

i want following printout appear in screen when run code: 

\begin{tabular}  \hline \\

for that, using following command on code:

std::cout<<"\begin{tabular}<< std::endl;  std::cout<<"\hline \\"<< std::endl;

and i'm getting following compiler message (regarding second line of code):

unknown escape sequence: '\h'

and following incomplete printout:

egin{tabular}  hline\

where in first 1 "\b" missing , first , last \ missing second sentence.

the question is: know how can print \ symbol text, such printed , not interpreted command, etc?

the backslash forms escape sequences in c++. have 2 options:

  1. double backslashes, la "\\hline \\\\" (the backslash escape itself, in tex).
  2. use c++11 raw strings, r"(\hline \\)" (the text enclosed parens inside quotes).

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...
