Answer 1

#include <stdio.h>

int main( )
{
   int n = 0;
   int input = 0;
   do
   {
      printf("Enter Number\n");
      scanf("%d", &n);
      if (!(n & n-1))
      {
         printf("Number is power of two\n");
      }
      printf("Do u want to continue. Press 0 to exit or 1 to continue\n");
      scanf("%d", &input);

   }
   while(input == 1);

   return 0;
}

In short, if output of number "n" & "n-1" results zero it means number "n" is power
