Hello, Is the endianess can be for the nibble boundaries ? Because i have defined a class, and try to access the array with a pointer of class type. typedef unsigned char uint8; class A{ public: uint8 a:4; uint8 b:4; }; int _tmain(int argc, _TCHAR* argv[]) { uint8 temp = 0xfa; A * ptr_a; ptr_a = (A *) &temp; printf("%x", ptr_a->a ); } To my surprise, a is 0x0a and not '0x0f' !. Any comments on this, will be very helpful, as i have a very big structure with access to nibble boundaries, will make it more complex for me to determine which bit goes where !!!
