C printing bits

Question

I am trying to write a program in C that prints bits of int. for some reason i get wrong values,

void printBits(unsigned int num){
    unsigned int size = si         


        

Answer 1

To address point two, I'd consider the following, which is simplified a bit for ease of understanding.

void printBits(unsigned int num)
{
   for(int bit=0;bit<(sizeof(unsigned int) * 8); bit++)
   {
      printf("%i ", num & 0x01);
      num = num >> 1;
   }
}
