Question

c++向量类问题错误求解答啊

#include#includeusing namespace std;class Vector3{ public: float x,y,z; // 构造函数 // 默认构造函数，不执行任何操作 Vector3() {} // 复制构造函数 Vector3(const Vector3 &a) : x(a.x), y(a.y), z(a.z) {} // 带三个参数的构造函数，三个值完成初始化 Vector3(float nx, float ny, float nz) : x(nx), y(ny), z(nz) {} // 重载比较运算符 bool operator==(const Vector3 &a) const { return x==a.x&& y==a.y&&z==a.z; } bool operator !=(const Vector3 &a) const { return x!=a.x||y!=a.y||z!=a.z; }
发不出来 呜呜 问题是

Answer 1

除了开头 #include#include 没写完整
还有后面少个}; 其他没错的，我这里编译可以通过
