When I do sizeof(unsigned long long) i get 8.
Afterwards I try to shift each unsigned char into its position along the destination unsigned long long variable, but I get a warning from the compiler that I am shifting beyond the type's capacity. That is not surprising since I am targeting 32 bit. Then I don't understand why the size of returns 8. Shouldn't it return 4 ?


No; long longs are always 8 bytes (64 bits). Ints are 4 bytes (32 bits) on both 32-bit and 64-bit architectures.
