10111  (23)
01100  (12)  Exclusive OR (XOR)
_____________________________

11011  (result = 27)

 

专属或有一些有趣特性.如果你排斥或多个本身 它把自己作为零点零零仍将与这两个因素不详定为零.

23 XOR 12 = 27
27 XOR 12 = 23
27 XOR 23 = 12

#include <stdio.h>
int main()
{
int num, key = 23;

printf("Enter a number: ");
scanf("%d", &num);

num ^= key;

printf("Exclusive OR with %d gives %d\n", key, num);
num ^= key;

printf("Exclusive OR with %d gives %d\n", key, num);

return 0;
}

bitwise恭维

bitwise恭维的是一个人的恭维经营toggles钻头,开机.如果是1,则定为0,如果是定而0比1.
