Is there a way to do something like this:

Code:

char sNames[7] = {'Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sun'};

Serial.print(sNames[1]);

And have it output 'Mon' ?

Seems silly to have to write a switch case to figure out what to print.

Code:

char* sNames[] = {
      "Sun" // 0
    , "Mon" // 1
    , "Tue" // 2
    , "Wed" // 3
    , "Thu" // 4
    , "Fri" // 5
    , "Sat" // 6
};

Serial.print(sNames[1]);

Danke!

NB - double quotes and a pointer.

Or,

Code:

char sNames[7][4] = {"Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sun"};

Code:

char sNames[7][4] = {"Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sun"};

On some calendars, Sat comes after Fri.

What does that actually do? And specifically, what does it do if the number of characters in an initialiser string is not 3?

That would create a matrix like this

	0	1	2	3
0	'S'	'u'	'n'	'\0'
1	'M'	'o'	'n'	'\0'
2	'T'	'u'	'e'	'\0'
3	'W'	'e'	'd'	'\0'
4	'T'	'h'	'u'	'\0'
5	'F'	'r'	'i'	'\0'
6	'S'	'a'	't'	'\0'

And the second question?

[Reply #9 on:]

Strings should be null terminated, hence 4 instead of 3.

Not sure whether you intended that to answer the question I asked, but it doesn't.

Simply allocate space that is not used. If it would have been declared as array[5] = "abc" it would contain:

0 1 2 3  4
a b c \0 X

where X is whatever junk was there to begin with. However, no you can also use strcpy(array, "abcd") and not worry about it.

That's if the initialiser is smaller than the declared size. What about the other case?

Absolutely anything can happen, horrible nondeterministic things eg. nasal demon will fly out.

There will be an error message from the compiler.
