An easy string-array question

I´m getting on the run with C and I need a tip for this. (Well, I think pointers and arrays in C are dificult to understand in the first days of training)

I have this declaration :

char strings[50][2];

Then.. how can I store values in this array that makes it look like this ?

 strings[1] = 'nel'
 strings[2] = 'sol'
 strings[3] = 'xel'

I can´t change the declaration to a similar one because I have some restrictions in PRO*C/C++ for Oracle, So the next declaration wont work:

 char *strings[3]   ---> This not good

And I need access the value in this way

  printf("\n",strings[1]);

I need also use (if I need to) compatible UNIX functions.

Regards!

Hi
use it like this
char strings[50][50];
strcpy(strings[1], "nel");
strcpy(strings[1], "sol");
strcpy(strings[1], "xel");
Hope this helps

Well... I´already tried that and didn´t work but in the run I notice that I have a error on my code :

char strings[50][2]

strings[1] = 'nel'
strings[2] = 'sol'
strings[3] = 'xel'

and when Im doing :

  strcpy(strings[1], "xel");

it didn´t work because of the difference in th length in 'xel' and the declaration of strings.

The point in here is why C does´nt check this insetad of writing in the strings :

strings[1] = 'nelsolxel'
strings[2] = 'nelsol'
strings[3] = 'xel'

well... that´s another question.

inpras : I´ll give you points in a grade C because I resolve my problem on my own but apreciate your help.

coming to answer of UR another question C being very flexible in pointers it won't check for array upper bounds ofcourse richie could have implemented it very easily but as U go on mastering it U will feel the advantages of it.
like accessing memory direcly and so on
Hope I cleared a little what doubt of URs
