If I have an array defined
const unsigned int lookup[] PROGMEM = {
0x0000,0xc0c1,0xc181,0x0140,0xc301,0x03c0,0x0280,0xc241,0xc601,0x06c0,0x0780,

0x81c1,0x8081,0x4040 };
Does the following line return the number of elements of the array?
(sizeof(lookup) / sizeof(int))
If not what will return the number of element of array lookup?
