>> operator in C??

Hi,

Here's the problem, hope someone can help:
I have read in 2 bytes from a file and have to decipher info from these two bytes based on bits!
My inofrmation is stored in the first 7 bits of the 2 bytes and there is other info in the last 9 bits of the 2 bytes. I was told that the >> or << operators can be used? Can anyone show me how I could use them to store say the first 7 bits into a variable called date? Thanks in advance.

Shifting is simple:

Code:

---

#include <stdio.h>
#include <stdlib.h>

int main ( void )
{
  unsigned x,
          date,
          bit = 21845U;
  date = bit << 9;
  for ( x = 0; x < 16U; x++ )
    printf ( "%d", !!( date & ( 1 << (unsigned)x ) ) );
  return EXIT_SUCCESS;
}

Output: 0000000001010101

Code:

---

#include <stdio.h>
#include <stdlib.h>

int main ( void )
{
  unsigned x,
          date,
          bit = 21845U;
  date = ( ( bit >> 7 ) << 7 );
  for ( x = 0; x < 16U; x++ )
    printf ( "%d", !!( date & ( 1 << (unsigned)x ) ) );
  return EXIT_SUCCESS;
}

Output: 0000000010101010
