WebNov 4, 2024 · Since we need to address at least 2 million positions, we need to store this address using at least 21-bits (because 2 20 > 2 million) -- regardless of how big an int is. Now, since sizeof (my 2-byte int) == 2, that means 2 positions in memory will "belong" to the int. Memory position 2,000,000 will hold "1100 0011".
