Deprecated code

I have a working Arduino sketch which I started writing in a state of complete ignorance, drawing on fragmentary clues from all over the internet. When I compile it, at this line ...

char* Day[] = {"","Sun","Mon","Tue","Wed","Thu","Fri","Sat"};

...I get the following warning message:
84:60: warning: deprecated conversion from string constant to 'char*' [-Wwrite-strings]
(actually repeated 8 times, presumably one for each string conversion)

I guess this means that the syntax I have used is somehow risky?

Despite the warning, the sketch does compile, and it works as intended. It bugs me, though - I'd like it to be perfect, and to know why it was wrong.

Please can anyone tell me how I could have coded this line better?

const char* Day[] = {"","Sun","Mon","Tue","Wed","Thu","Fri","Sat"};

This way it works without warnings. The strings are const, aren't they? :wink:

Aha, I get it!! Thank you so much, Whandall. That would probably have bothered me for months without help.
