Question

i have some bidimensional arrays like:

int shape1[3][5] =  {1,0,0,
             1,0,0,
             1,0,0,
             1,0,0,
             1,0,0};
int shape2[3][5] =  {0,0,0,
             0,0,0,
             0,1,1,
             1,1,0,
             0,1,0};

and so on.

How can i make an array of pointers to those?

I tried the following, but they don’t work (warning: initialization from incompatible pointer type):

int *shapes[]=  {&shape1,&shape2};

int *shapes[]=  {shape1,shape2};

int **shapes[]= {&shape1,shape2};

Any help?

Updated Fixed type. Thanks j_radom_hacker for bringing this to my attention!

[EDIT: Actually the type here was not correct — see Robert S. Barnes’ answer for the correct type to use.]

Figure out the type of shape1 and shape2 first:

typedef int (*shape_array_t)[5];

Now use this:

shape_array_t sat[] = { shape1, shape2 };
