在C语言中 下面的程序输出结果各是多少？

Question

# include <stdio.h>
int main (void)
{
unsigned char result;
int a = 2;
int b = 4;
int c = 6;
int d = 8;
result = a & c;
printf("result = %d\n",result);
result = b | d;
printf("result = %d\n",result);
result = a ^ d;
printf("result = %d\n",result);
result = ~a;
printf("result = %d\n",result);
return 0;
}

Answer 1

2--00000010
4--00000100
6--00000110
8--00001000
他们做上面的运算可以自己分析一下的。
结果就是

Answer 2

result=2
result=12
result=10
result=253

经过试验了

Answer 3

result = 2
result = 12
result = 10
result = 253
