Two dimensional array
PostPosted: Tue Mar 08, 2005 2:42 pm     Reply with quote
Hi folks,

can anybody reveal me how to initialize an two dimensional array?

For a menu-driven application i like to store all the text-strings into such an array and retrieve it via the first dimension as follows:

static constant char text[][] = {1,2,3,4,5...},{"Hello","Welcome","Wait",
"Your Code","...",....};

Butjavascript:emoticon('Mad') the compiler does not like it and the manual does not say anything about it.

Therefore i am asking for your help.

Saludos

Jorge

If you have a question about compiler behavior, the easiest way
to answer it is to write a test program and examine the .LST file
or look in the Program Memory window in MPLAB. Example
of two dimensional array in ROM:
Code:
#include <16F877.H>
#fuses XT, NOWDT, NOPROTECT, BROWNOUT, PUT, NOLVP
#use delay(clock = 4000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, ERRORS)

const char messages[5][10] = {"Hello", "ABC", "12345", "World", "Today"};

//============================
main()
{
char c;
char i;
char j;

c = messages[i][j];

while(1);
}

Looks like you are wanting pointers to consts again. Remember that they are not supported for this compiler.

Hi Mark,

thanks for reply. No, this is what I learned already. It was the way how to initialize the two dimensions. Through your example it is clear now. Unfortunately the manual was not very helpful.

Saludos
