Question

Jus check out this program.Logically it seems fine but its giving 000000000000000000000 for everything

#include<stdio.h>
void main()
{
  int n=25,k=32;
  printf("binary equivalent\n");
  while(k!=0)
  {
    if((n>>1&0x01)!=0)
      printf("1");
    else
     printf("0");
    k--;
  }
}

Answer 1

You don’t ever change n.

Don’t try and cram everything into one line, be a little more verbose so that things are clearer.

while(k!=0)
{
 if((n & 0x01) != 0)
  printf("1");
 else
  printf("0");
 k--;
 n >>= 1;
}
