copying a 2-dimension array into another

[johnny]

Hi,. I have an arry like:

float arr[4][5];

I want to copy the content of each element in arr to this array

float target[4][5];

I know if I make this it will work:

for(i=0;i<4;i++)
for(j=0;j<5;j++)
target[i][j]=arr[i][j];
But, How could I make it also with memcpy ??? Or more simple wih another
function ?

Tnx
Johnny

include <string.h>

and try: memcpy(target,arr,sizeof(arr));
If arr is a pointer as opposed to array this won't work unless you
make some changes.
