Question

Assuming I have char “C” whose ascii code is 0110 0111. How can I iterate over its bits? I would like to build a vector from these 1’s and 0’s….

You can easily iterate over them using bitwise operators:

char c = 'C';
for (int i = 0; i < 8; ++i)
{
  // extract the i-th bit
  int b = ((c & 1<<i) >> i);
  // b will be 1 if i-th bit is set, 0 otherwise

  // do whatever you want with b
}

you can optimize it (as suggested in comments):

int b = ((c >> i) & 1);
