convert array to two dimensional array by pointer

Question

Is it possible to convert a single dimensional array into a two dimensional array?

i first tought that will be very easy, just set the pointer of the 2D array to the

Answer 1

I know you specificed pointers... but it looks like you're just trying to have the data from an array stored in a 2D array. So how about just memcpy() the contents from the 1 dimensional array to the two dimensional array?

int i, j;
int foo[] = {1, 2, 3, 4, 5, 6};
int bla[2][3];
memcpy(bla, foo, 6 * sizeof(int));
for(i=0; i<2; i++)
   for(j=0; j<3; j++)
      printf("bla[%d][%d] = %d\n",i,j,bla[i][j]);

yields:

bla[0][0] = 1
bla[0][1] = 2
bla[0][2] = 3
bla[1][0] = 4
bla[1][1] = 5
bla[1][2] = 6

That's all your going for, right?
