can someone please explain how does the sizeof() and the mask help me on converting from dec to binary? and also bit shift?
this what i got now: i followed the book says to bit-wise & the mask and my input;
but the mask is ending with 0s(0x80000). isnt that will make all the num into 0? and i have no idea what does the sizeof() and the bit-shift works?
thanks
