how to initialize an array?

Question

I have a 3dimensional array, how do I initialize it to a default value without having 3 loops.

dummy[4][4][1024]

, how do I initialize all the elements to 12?

Answer 1

Since the 3-d array is a contiguous block of memory, you can view it as a 1-d array

int i, *dummy2 = &dummy[0][0][0];
for(i = 0; i < 4*4*1024; ++i)
    dummy2[i] = 12;

Answer 2

Come on guys - let's do it the simple way that always works:

for(int i = 0; i &lt 4; i++)
{
  for(int j = 0; j &lt 4; j++)
  {
    for(int k = 0; k &lt 1024; k++)
    {
      dummy[i][j][k] = 12;
    }
  }
}
