Bigger constant lenght

Using Arduino Programming Questions
#1

Hi
I have a question.

I can only create a single constant ? i mean like only 1 symbol?
I want to create constants with b1,b2,b3,b4 value and soo on but i cant.
They are not working when not highlighted.
Any tips?
Thanks.

#2 
const unsigned int vt_start = 'B1';

It'll compile and work, but whether it will do what you want, I don't know, because you don't tell us.

#3

AWOL:

const unsigned int vt_start = 'B1';

It'll compile and work, but whether it will do what you want, I don't know, because you don't tell us.

Thanks, gotta try

A character ('char') variable can only contain one character:

char one_character = 'X';

An integer ('int') variable can contain up to two characters:

int two_characters = 'XY';

A long integer ('long') variable can contain up to four characters:

long four_characters = 'WXYZ';

A character array can contain a string of characters:

char string[] = "XYZABCDEFG";

(Note the use of double-quotes for a "string of characters" and the single quotes for 'character constants'. An additional character of value 0 is added to the string to mark the end.)

Any of them can be made constant by adding the 'const' keyword.

johnwasser:
A long integer ('long') variable can contain up to four characters:

long four_characters = 'WXYZ';

The type of 'WXYZ' is int so this will not work as intended if you have 16-bit ints.
