WebMay 20, 2024 · When an object of size 10 is allocated, it is allocated from the 16-byte pool for objects 9-16 bytes in size. So, even though it contains only 10 bytes of data, it will cost 16 bytes of memory. If you allocate 1,000,000 objects of size 10, you actually use 16,000,000 bytes and not 10,000,000 bytes as you may assume. WebThe more bits allocated to an integer, the higher its largest value can be. The general formula for how many values an integer can take on is 2^n, where n is equal to the number of bits.
