pointer to code memory

unsigned char code **ptr;//pointer to code memory

Did you copy&paste this from your code ?

If yes, then it's not a pointer to code memory. It's a pointer to a pointer. However, I'm not quite sure if it is a pointer a generic pointer in code memory, or a pointer in the default memory space to a pointer to code memory. Maybe some of the experts could clear this up.

You've fallen prey to the common misconception that pointers and arrays are fully interchangeable in C. They're not.

In particular, a pointer to an array of a multi-dimensional array is not constructed as a pointer-to-pointer-...to-element.

Correct code (setting aside the additional complication of the "code" keyword) would be any of

unsigned char (*ptr_to_whole_array)[120][5] = &table;
unsignec char (*ptr_to_first_row)[5] = table;
unsigned char *ptr_to_element = table[0];

thanks every one
and special thanks to

i did as u said

and i got the result

i think i got to work more on this arrays concept
i previously worked on the two dimensional arrays but never faced this kind of situation

any way thanks to all of u
