If you use double quotes, it is done like this...
char dash[9][9] =
{
"123456789",
"abcdefghi",
"qwertyuio",
"987654321",
"ihgfedcba",
"oiuytrewq",
"zxywvutsr",
"allstarpy",
"mondolori"
};
Otherwise, use single quotation marks. Note that you can get a warning such as
error: initializer-string for array of chars is too long [-fpermissive]
from G++ 4.6.2 (compiler options -Wall -Wextra).
