Characters to binary... hexadecimal to binary

I did some research, and only c++ has unions and single-bit data structures. Now, through the demonic ingenuity of my thought processes, i recalled how i did the bit access.

Code:

union char_bin_hex {  //edit: changed struct to union
  char ch;
  union char_to_bin bits;
  union char_to_hex dibits;
}

struct char_to_bin {  //edit:  changed union to struct
  unsigned b1: 1
  unsigned b2: 1
  unsigned b3: 1
  unsigned b4: 1
  unsigned b5: 1
  unsigned b6: 1
  unsigned b7: 1
  unsigned b8: 1
}

struct char_to_hex {  //edit: changed union to struct
  unsigned d1: 2
  unsigned d2: 2
  unsigned d3: 2
  unsigned d4: 2
}

All you do is put the char into char_bin_hex.ch and access the individual bits/dibits through char_bin_hex.bits.b1 etc and char_bin_hex.dibits.d1 etc.

Hope this helps! I will work on a function tht works with this when iget back frm church & lunch.

Is it just me or did you get that a little backwards? The unions should be structures, and the structure should be a union. Or else i'm an idiot. (Then again i've never done anything like that before)

Yeah! You're right!

I am editing that now, so don't get confused by eibro's post guys...

Now i can actually make the function correctly!
