WebNov 7, 2013 · The order of allocation of bit-ﬁelds within a unit (high-order to low-order or low-order to high-order) is implementation-deﬁned. The alignment of the addressable storage unit is unspeciﬁed. So, depending on "addressable storage unit" compiler picks, your a and b may end up in different 'storage units', depending on compiler specifics. WebThis is significant: consecutive (non-zero width) bit-fields are merged into a single memory location, while a bit-field followed by a non-bit-field are distinct memory locations. Your first structure has a single memory location, your second has three. You can take the address of the b member in your second struct, not in your first.
