Question

I asked the question here and now i would like to reverse this procedure

I have an unsigned short that represents a bit pattern, I would like an array of bool[16] that has true or false set for the corresponding bit in the unsigned short.

so far i have

where binary 2 is an unsigned short, that has the bit pattern i wish to unpack.

unsigned short i;
i = 1<<(sizeof(unsigned short) * 8 - 1);

while (i > 0) {
    if (binary2 & i)
        printf("1");
    else
        printf("0");
    i >>= 1;
}

but i seem to be missing the first bit in my pattern and shifting the remaining ones.

Answer 1

how about this.

void ExtractBits(int pattern, int array[16])
{
   for (int ii = 0; ii < 16; ++ii)
   {
      array[ii] = pattern & 1;
      pattern = pattern >> 1;
   }
}
