Copy 2D array to another 2D array.

[OwnedPeace]

Hello. Asking for help about copying 2D arrays.
For example :
I have an array - float a[50][50]. Users input numbers themselves. How can i copy those numbers to another array - float b[50][50] ?

for (int x=0 ; x < 50; x++)
{
  for (int y=0 ; y < 50; y++)
  {
    b[x][y] = a[x][y];
  }
}

Alternatively;

memcpy (b, a, 50*50*sizeof(float));

or
std::copy(&a[0][0], &a[0][0]+50*50,&b[0][0]);

@Repeater , thanks, was using the same thing, but seems that something was missing. This one worked :)
