Question

While trying to compile the Maze Generator/Solver in C as present in rosettacode in Visual Studio 2010, I am facing issue during compilation.

The following line

#   define SPC "　"
wchar_t glyph[] = L""SPC"│││─┘┐┤─└┌├─┴┬┼"SPC"┆┆┆┄╯╮ ┄╰╭ ┄";

is throwing an Error

1>d:\projects\maze_cpp\maze_cpp\main.cpp(14): error C2308: concatenating mismatched strings
1>          Concatenating wide "" with narrow "?????? ??? ?"

Considering my limited knowledge with Unicode, and the unfriendly description of the error in MSDN, I am puzzled about the problem and how to solve it

Answer 1

You need to escape the "s in the wide string literal:

wchar_t glyph[] = L"\"SPC\"¦¦¦-++¦-+++---+\"SPC\"?????? ??? ?"; 

EDIT:

I missed the SPC macro (as already posted by Luchian and jrok):

#define SPC L"  "
wchar_t glyph[] = L"" SPC L"¦¦¦-++¦-+++---+" SPC L"?????? ??? ?";
