Question

I have a 2-dimensional integer array of constant size which I declare as

int array[SIZE_1][SIZE_2];

I would like to declare a pointer p so that I can assign a “row” of the 2-dimensional array to it, i.e.

p = array[index];

I have tried declaring p as

int (* p)[SIZE_2];

but this gives me a "assignment from incompatible pointer type" warning (GCC on MinGW).

So how do I declare p correctly?

Answer 1

Your are pointing to an array of integers(Row):-

 int *p = array[index];
 so,
 p[1] == array[index][1]; 

This also works:-

int array[SIZE_1][SIZE_2];
int (*p)[SIZE_2] = array;
