C中的按位运算符

#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 );
