array of chars from array of array of chars

[GMVS]

hello

i got a bidimensional array of chars

assume it looks like this

const char array[3][17]={"mary",

                                      "has a",

                                      "lamb"};

1) can i safely assume the matrix is gonna end like this?

0	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15	16
m	a	r	y	/0
h	a	s	0x20	a	/0
l	a	m	b	/0

assume i have a function like this

void function(char something[]);

2) is there any easy way to send just the second row of array to the function??

because if i write

function(array[1][0]);

this thing is gonna break

3) or should i make a new unidimensional array, copy the info from the other to this one with a for cycle and then send it?

thanks

Hello,

1. When initialising the array, the individual strings will need to be separated using commas, and the array definition should end with a semicolon.
char array[3][17] = {"mary",  "has a", "lamb" };

If you are expecting the array data to be located within flash memory, you will need to use the const modifier.

2. The function is expecting a pointer to the first element of a single dimension array.  To send the second element of the two-dimenional array to the function you can use array[1] as the parameter.  This should give identical results to the alternative &array[1[[0].

if i had to make fors for every time i want to use the routine i was gonna waste a hell of time
