C++ int as bool
Webc++位运算判断某值的二进制中1的个数，某值是不是2的n次方. n&(n-1)作用：将n的二进制表示中的最低位为1的改为0，先看一个简单的例子： n 10110(二进制），则(n-1) 10101 》n&(n-1) 10100 可以看到原本最低位为1的那位变为0。 WebC++ 正确使用集合交叉点的方法 struct-Cord { int x_线； 内y_线； 跳线（intx=0，inty=0）：x_跳线（x），y_跳线（y）{} bool操作员,c++,set,intersect,C++,Set,Intersect,上述代码的编译失败。有没有建议如何在示例中正确使用set\u intersection？
