0 c bit-manipulation bitwise-operators uint64 bitwise-and
我有以下代码,只是检查uint64_t是否是偶数,我打算使用按位AND操作来检查,但它似乎没有工作.
这是我认为首先工作的代码:
int n;
scanf("%d",&n);
for(int i = 0; i < n; i++){
uint64_t s,d;
scanf("%llu %llu",&s,&d);
//try for x
uint64_t x;
bool stop = false;
x = s + d;
printf("%llu",x&1ULL); \\ This prints 0 when the number is even but
if(x&1ULL==0ULL){ \\ This check always returns false
printf("%llu",x);
x/= 2;

如果数字是奇数或偶数,则此代码始终打印输出0或1,但if语句始终返回false.我究竟做错了什么?谢谢
