my mate is new to C++ and he uses the dev c++ compiler, one of the best around or so i hear.
anyway, when he comiled his program, he got no compile errors, but a warning that said:
unknown escape sequence '\/' on line 8 which was just text
using printf and "\n\n"
he justs wants to know what its telling him
when you want to use a \ literally, you must escape it using another \
if you don't the compile thinks you're trying to escape the next character...
i don't know all of them by heart, but \a, \n, \b, \r, etc are all escape sequences. if the compiler come across one that it doesn't recognize, it gives you a warning....
try this
i'm thinking this should printCode:int main() { char x[] = "abc\def"; char y[] = "abc\\def"; cout << x << endl << y << endl; }
abcef
abc\def
i seem to have GCC 3.3.4
But how do i start it?
I dont have a menu for it or anything.
somewhere, he has "\/"... basically, what that is doing is trying to find an escape character '/', which there is none... all you have to do is find that line and type "\\/" instead... that is, of course, if he wanted to print "\/"
