C++/C (&~)运算和(&)运算
本文共 261 字，大约阅读时间需要 1 分钟。
一 小例子
今天看文章，看到这两个运算符，了解一下，直接放代码比较直观
int main(){ int m = 200; int n = 64; int l = m&(n - 1); int o = m&~(n - 1); cout << "m/n余数为" << l << endl; cout << "m向n的倍数逼近，最近的是" << o << endl; getchar(); return 0;} 结果
可以看到： 运算符m&n的结果是求出m/n的余数
运算符m&~n的结果是求出m向n的倍数逼近，最近的一个
