C语言按位运算符

#include <stdio.h>

main() {

   unsigned int a = 60;    /* 60 = 0011 1100 */  
   unsigned int b = 13;    /* 13 = 0000 1101 */
   int c = 0;           

   c = a & b;       /* 12 = 0000 1100 */ 
   printf(Line 1 - Value of c is %d\n, c );

   c = a | b;       /* 61 = 0011 1101 */
   printf(Line 2 - Value of c is %d\n, c );

   c = a ^ b;       /* 49 = 0011 0001 */
   printf(Line 3 - Value of c is %d\n, c );

   c = ~a;          /*-61 = 1100 0011 */
   printf(Line 4 - Value of c is %d\n, c );

   c = a << 2;     /* 240 = 1111 0000 */
   printf(Line 5 - Value of c is %d\n, c );

   c = a >> 2;     /* 15 = 0000 1111 */
   printf(Line 6 - Value of c is %d\n, c );
