order of array subscripts

#include <stdio.h>

char uu[5][4];

main()
{
printf("%p %p %p\n",&uu[0][0],&uu[1][0],&uu[0][1]);
}

gives

C:\a>kwik
0040C1F0 0040C1F4 0040C1F1


This suggests the rightmost array subscript iterates most quickly, so
uu is an array of 5 of array of 4 of char.

Is that understanding correct? Sorry for such a trivial question but I
think my understanding hitherto has been wrong.
