Array base address = ‘a’

// To access the second element of the array
// we can take the index * size of an element.
//
*(uint64_t*)(a + (1 * sizeof(uint64_t))) = 10;

// The above is the same as doing this.

a = base of array = 00 (like diagram)
//
// Access first element
//
*(u64*)(a + (0 * sizeof(u64))) // => *(u64*)(a + 0) => read 64-bit integer @ base of 'a' (address 00)
//
// Access second element
//
*(u64*)(a + (1 * sizeof(u64))) // => *(u64*)(a + 8) => read 64-bit integer @ base of 'a' + 8 (address 08)
